'Believe that I Am': Encountering John's Christ in the Light of Isaiah (Part 3)

100-Word Summary

The seven 'I am' (egō eimi) sayings of Jesus in the Gospel of John are shown to contain striking allusions to deutero-Isaiah, implying that to understand their meaning we must see them as echoes of God's egō eimi sayings in the Septuagint version of Isaiah 40-55. Proceeding with this line of interpretation, we reach the conclusion that John presents Jesus as the God of Israel. Jesus' identification with God is not exhausted by his function as God's agent, since his 'I am' sayings are primarily about himself. Instead, they reflect his ontological status as the pre-existent divine Word and Son.

Erratum: The author regrets that an earlier version of this article reported that the form of the verb ginomai in John 8:58 is egeneto (aorist indicative); it is in fact genesthai (aorist infinitive). The difference, however, has little bearing on the meaning in this case.

1. Introduction

In the first article in this series, we provided a brief introduction to the Book of Isaiah and the Gospel of John, and gave a very brief overview of the close literary relationship between them. In the second article, we went into much more detail about specific allusions to Isaiah in John, focusing primarily on a discussion between Jesus and the Pharisees in John 8:12-30. One of our key findings was that Jesus' language in this passage is saturated with allusions to Isaiah 43 in the Septuagint (an ancient Greek version of the Old Testament). In particular, the lines 'For if you do not believe that I am, you will die in your sins' (John 8:24) and 'When you lift up the Son of Man, then you will realize that I am' (John 8:28) were seen to be allusions to Isaiah 43:10 LXX ('so that you may know and believe and understand that I am'). In this article we are going to more closely study the intriguing expression 'I am' (Greek: egō eimi) as used by Jesus in the Gospel of John. The insight we bring from the previous study is that, in order to understand what egō eimi means in John, we must first understand what it means in Isaiah LXX.

Attempts to interpret the 'I am' (egō eimi) sayings in John, particularly in the context of theological debates over Jesus' deity, often focus on the question of whether the expression alludes to the Divine Name as explained to Moses in Exodus 3:14. This approach can easily become bogged down in the difficult question of what the Divine Name (in Hebrew, ʾęh^eyęh ʾ^ašęr ʾęh^eyęh) means. In deutero-Isaiah (Isaiah 40-55), however, we have a Hebrew expression that corresponds more exactly to egō eimi, that indeed is translated as egō eimi in the Septuagint. Moreover, we have already shown in Part 2 that at least one of the egō eimi sayings in John alludes to one of the egō eimi sayings in deutero-Isaiah. Thus, we may bracket out the issue of the Divine Name and and focus on what is known.

2. ʾ^anî hûʾ and egō eimi in deutero-Isaiah

The expression 'I am he' is used by God nine times in the Hebrew Bible:¹ once in Deuteronomy and eight times in deutero-Isaiah (Deut. 32:39;² Isa. 41:4;³ 43:10,⁴ 13,⁵ 25;⁶ 46:4;⁷ 48:12;⁸ 51:12;⁹ 52:6¹⁰).¹¹ In seven of these instances the Hebrew text is ʾ^anî hûʾ (literally, 'I he,' with the verb 'am' implied). The other two instances have the more emphatic ʾânōkî ʾânōkî hûʾ ('I, I [am] he'; these are Isa. 43:25 and 51:12).¹² The significance of the phrase in deutero-Isaiah, which always has God as its speaker, is summarised by Catrin H. Williams:

Deutero-Isaiah, who may have been inspired by the self-proclamation that brings the Song of Moses to its climax [Deut. 32:39], presents אני הוא as a succinct expression of Yahweh's uncontested claim to exclusive divinity. His unique capacity to predict and control events, having fulfilled his promises in the past (41:4; 43:10), serves as a guarantee to Israel that Yahweh will continue to support and deliver his people (43:13; 46:4), for he is the eternally active God, ראשון and אחרון a(41:4; 44:6; 48:1), the Creator of all things (48:13).¹³

The expression is used interchangeably with 'I am God' and 'I am YHWH' (see, e.g., Isa. 43:10-15); it is just as definitive a declaration of God's unique deity that separates him from all other reality. The Septuagint renders ʾ^anî hûʾ into Greek as egō eimi and ʾânōkî ʾânōkî hûʾ into Greek as the double egō eimi egō eimi. There are nine occurrences in the Septuagint of God's self-declaration egō eimi without a predicate.¹⁴ These are Deut. 32:39,¹⁵ Isa. 41:4,¹⁶ 43:10,¹⁷ 43:25,¹⁸ 45:18-19 (twice),¹⁹ 46:4 (twice),²⁰ and 51:12.²¹ (The list does not correspond exactly to the list of Hebrew ʾ^anî hûʾ/ʾânōkî ʾânōkî hûʾ passages above.)²² In Isaiah 47:8, 10 LXX, God twice accuses the daughter of Babylon of saying in her heart, 'I am (egō eimi), and there is no other,' and declares that destruction shall befall her.²³ The implication is that for anyone other than God to make such a declaration would be blasphemous. 'I am' (egō eimi) in these passages thus clearly functions as a 'theophanic formula,'²⁴ a claim to absolute uniqueness that only God can make.²⁵

3. The Meaning of egō eimi in Greek

It is important to note that the Greek phrase egō eimi has an mundane meaning in ordinary human conversation. It can function as a simple affirmation about oneself ('I am') or as a way of identifying oneself as a particular person under consideration ('I am he'; 'it is I'), which we will refer to as a 'self-identificatory affirmation' (SIA). In the Septuagint, this usage can be seen for instance in 1 Kingdoms (1 Samuel) 9:18-19. Saul approaches Samuel (whom he does not know) and says, 'Tell, now, which is the house of the seer?' To which Samuel replies, 'I am he' (egō eimi).²⁶ This ordinary SIA sense also occurs in the New Testament, including in John. After Jesus heals a blind beggar, others dispute whether the man before them is really the one who used to sit and beg. The man says, 'I am' (egō eimi, John 9:9). A number of other such occurrences can be found in the Synoptic Gospels, usually on the lips of Jesus or with reference to Messianic claims.²⁷

A key question, therefore, as we come to Jesus' use of egō eimi in John, is whether he is using it in the ordinary SIA sense, to identify himself as some person under consideration (e.g., the Messiah, or Jesus of Nazareth), or whether he is using it in the loftier sense of deutero-Isaiah, thus making a claim to deity, to be the one Lord God who created the world, who is eternal, and who will redeem Israel. The contention here is that in some of the passages a double meaning is present, and both meanings are in play. We saw in Part 1 that John is fond of double meanings, and we saw in Part 2 that Jesus' egō eimi saying in John 8:24 clearly alludes to God's egō eimi saying in Isa. 43:10 LXX (whereas the Pharisees miss the double meaning and, thinking Jesus means 'I am he' in the SIA sense, ask, 'Who are you?')

In what follows, we will examine the individual egō eimi sayings in John. We will argue that not only those in John 8:24, 28 but also several others contain echoes of deutero-Isaiah that allow us to recognise them as veiled divine claims.

4. The Seven egō eimi Sayings of Jesus in John

 4.1. John 8:24: 'If you do not believe that I am, you will die in your sins' 

These two sayings will be discussed only briefly, since they were dealt with in Part 2. We found there that Jesus' discourse in John 8:12-30 contains numerous conceptual parallels with and allusions to deutero-Isaiah LXX. These include:

• Having light vs. walking in darkness (John 8:12 vs. Isa. 9:2, 50:10 LXX)
• God and his Servant as two witnesses (John 8:16-18 vs. Isa. 43:10 LXX)
• Contrast between those who belong to earth and the transcendent one (John 8:23 vs. Isa. 41:24; 55:9)²⁸
• The expression, 'in your sins' (John 8:24; Isa. 43:24 LXX)
• The expression, 'believe that I am' (John 8:24; Isa. 43:10 LXX)
• The expression, 'at/from the beginning the one who speaks' (John 8:25; Isa. 43:9, 45:19, 48:16 LXX)
• The reference to entering into judgment (John 8:26; Isa. 43:26 LXX)

Thus it is clear that the 'I am' saying of John 8:24 is rooted in an Isaianic background and above all in Isa. 43:10 LXX. Thus Jesus is claiming for himself precisely what God is claiming for himself with the 'I am' sayings of deutero-Isaiah: he is making the claim that 'I am God, and besides me there is none who saves' (Isa. 43:11 LXX). For that reason, to fail to believe in him is to forfeit salvation.²⁹

 4.2. John 8:28: 'When you lift up the Son of Man, then you will realize that I am'

This saying falls within the same discourse as 8:24, and thus what we have already said above about the Isaianic background to this passage applies here. Moreover, in Part 2, we discussed the rich double meaning of the term 'lifted up' in John (crucified/exalted), which is also rooted in deutero-Isaiah. Thus the 'I am' saying of John 8:28 is also best understood in terms of this Isaianic background. Indeed, 'then you will realize that I am' repeats the idea of v. 24 (which was expressed negatively), and both echo Isa. 43:10 LXX with two of the three Greek verbs used there: 'so that you may know [John 8:28] and believe [John 8:24] and understand that I am.' What is new in John 8:28 is the paradoxical notion that it is above all through his death, his 'lifting up,' that Jesus' deity is recognizable.

 4.3. John 8:58: 'Before Abraham came into being, I am'

This saying is the climax of the discourse and dialogues of John 8:12-59. Vv. 12-30 contain an exchange between Jesus and the Pharisees, and vv. 31-59 continue uninterrupted with an exchange between Jesus and 'those Jews who believed in him' (though they prove instead to be hostile), apparently in the same setting. The focus of the discussion shifts to paternity (his and theirs), and especially their relationship to the patriarch Abraham. Jesus claims in John 8:56, 'Abraham your father rejoiced to see my day; he saw it and was glad.' This remark parallels the Fourth Evangelist's editorial comment in John 12:41 (after quoting from Isaiah's throne vision in Isaiah 6), 'Isaiah said this because he saw his glory and spoke about him.' Since this comment refers to Isaiah's actually having seenJesus (as the Lord high and lifted up in his temple), it is unlikely that in John 8:56, Jesus is referring merely to Abraham during his lifetime 'seeing' the Messiah with eyes of prophetic faith. A more direct communion between Abraham and Jesus is in view. Sensing this, 'the Jews' respond with incredulity: 'You are not yet fifty years old and you have seen Abraham?' This produces the climactic claim: 'Amen, amen, I say to you, before Abraham came into being, I am.'

The earlier 'I am' sayings in John 8:24, 28 had seemingly not been understood by Jesus' opponents. As already mentioned, the Pharisees' question 'Who are you?' in 8:25 shows that they understood egō eimi in its ordinary SIA sense ('I am he'; 'it is I'). However, the remark in 8:58 is unmistakable, and his opponents immediately seek to stone him. Challenged as to whether he might have seen Abraham, he has not only claimed to have pre-existed Abraham, but has done so using the egō eimi formula that God uses in deutero-Isaiah to declare his unique deity. Translations such as the KJV, ESV, and NRSV, which render the saying, 'Before Abraham was, I am,' fail to convey the full sense of the verb genesthai: 'came to be/came into being.' It is not just the 'when' of existence that is being contrasted here but the kind of existence. The status of a creature—even one as renowned as Father Abraham—who 'comes to be' is contrasted with the One who simply 'is.'

Like John 8:24 and 8:28, the 'I am' saying in John 8:58 closely parallels Isaiah 43:10 LXX. There, God declares, '...I am (egō eimi). Before me no other god came to be (egeneto), and none will be after me.' Here, too, God sets forth his unique deity by contrasting his absolute existence ('I am') with the 'coming to be' of other realities. Another such parallel is found in Isaiah 48:16 LXX, where a mysterious speaker who identifies himself as sent by the Lord and his spirit states, 'From the beginning I have not spoken in secret; when it happened (or 'came to be'; Greek: egeneto) I was there.' This passage has already been discussed in Part 2.³⁰ In both John 1:1-3 and 8:58, as in both Isaiah 43:10 and 48:16 LXX, the time-transcending 'being' of deity (described using a present or imperfect tense of eimi is contrasted with the 'coming to be' in time of other reality (described using an aorist form of ginomai).

If we cast our net wider than deutero-Isaiah, we can find other verbal and conceptual parallels to John 8:58 in the Septuagint. The most striking of these is in Psalm 89:2 LXX (90:2 Eng), where the psalmist addresses the Lord, 'Before mountains were brought forth and the earth and the world were formed, and from everlasting to everlasting you are.' The Greek for 'you are,' su ei, is the second-person equivalent of egō eimi. Thus we have the same pattern as John 8:58: before some created reality (in this case mountains, earth, world) came to be (aorist infinitive of ginomai), the Lord is. The inclusion of the words 'from everlasting to everlasting' convey explicitly what is implicit in the egō eimi sayings: that the quality of existence referred to as 'I am/you are' is eternal. Further Septuagint parallels to John 8:58 can be found. They cannot detain us here,³¹ but the parallels we have seen in deutero-Isaiah and Psalm 89 compel us to conclude that in John 8:58, Jesus' provocative declaration amounts to a claim of deity and eternal pre-existence.

 4.4. John 13:19: 'so that when it happens you may believe that I am'

In John 13:18-19, after making reference to his betrayer with a scripture quotation, Jesus declares to his disciples, 'From now on I am telling you before it happens, so that when it happens you may believe that I am.' The form of this 'I am' saying is very similar to that of John 8:24 (but this time worded positively) and even closer to that of Isaiah 43:10 LXX in Greek.³² One of the characteristics by which God's unique deity may be known, according to deutero-Isaiah, is his ability to declare events before they happen.³³ It is just this characteristic that Jesus claims here will enable his disciples 'to believe that I am.' Hence, the deutero-Isaianic background of this egō eimi is clear.

 4.5. John 6:20: 'I am; do not be afraid'

We now move backward in the Gospel to egō eimi sayings prior to the discourse in John 8. John 6:16-21 describes the episode of Jesus walking on the sea during a storm, and includes the only one of John's egō eimi sayings that to be paralleled in the Synoptic Gospels (see Matt. 14:27; Mark 6:49). Upon seeing Jesus (and presumably not recognising him), the disciples became afraid. Jesus then declares, 'It is I. Do not be afraid' (egō eimi, mē phobeisthe). John differs from the Synoptic accounts on what happens next. In Mark and Matthew, Jesus gets into the boat (in Matthew's case, only after Peter walks on water), the wind dies down, and the disciples are amazed. In John, 'They wanted to take him into the boat, but the boat immediately arrived at the shore to which they were heading.'

It is clear that in John 6:20, as in the Synoptic parallels, egō eimi carries its ordinary sense as a way of identifying oneself (an SIA). Jesus is saying, 'It's me, Jesus.' The question is whether this is all he is saying. In Matthew and Mark, that may be the case.³⁴ In John, however, we know (based on the foregoing analysis) that Jesus is going to say egō eimi with a higher, more profound meaning at least four subsequent times, and this raises at least the possibility that such a meaning is intended here. This possibility exists even though (a) it may well have escaped readers/hearers on their first time through the Gospel (since they would encounter it before John 8), and (b) we know almost for certain that the Fourth Evangelist did not construct this egō eimi saying, but took it from the tradition.³⁵ What will help us to move from guesswork to insight about the meaning of egō eimi in John 6:20 is to read the passage in light of its Old Testament, and particularly Isaianic, background.

One of the characteristics of Yahweh in the Hebrew Bible is his power over the sea. The event that demonstrates this par excellence is his parting of the Red Sea and defeat of the Egyptian army (Exodus 14). Readers of the 'walking on the water' narrative (in Matthew, Mark, and John) have long seen in Jesus' walking on the sea a narrative allusion to this power of Yahweh. An oft-quoted passage in this respect is Job 9:8 LXX, which says of the Lord that he 'walks on the sea as on dry ground,' using language very close to that of the Gospels.³⁶ God's power over the sea also features in deutero-Isaiah. In Isaiah 43:16 (alluding to the Exodus), the prophet writes that the Lord 'provides a way in the sea, a path in the mighty water,'³⁷ which is precisely what Jesus does in this narrative: he not only provides a path for himself, but he miraculously conveys his tempest-tossed disciples to the other side, as God did for Israel at the Red Sea.³⁸ No early Jewish reader of John 6:16-21 with a sound knowledge of salvation-history could fail to be reminded of the Exodus narrative and the subsequent scriptures that retell it in terms of God making a way in the sea.

A second feature of this egō eimi saying that should not escape our notice is contained in the words, 'Do not be afraid.' This comforting phrase occurs frequently in Scripture, but never (at least in the Septuagint) is it pronounced more frequently by God than in Isaiah, and especially deutero-Isaiah. God repeats this to his people in Isaiah 40:9,³⁹ 41:10,⁴⁰ 41:13-14,⁴¹ 43:1,⁴² 43:5,⁴³ and 44:2.⁴⁴ Of special interest is Isaiah 51:7-15, which reassures Israel that they need not be afraid precisely in the context of an 'I am' saying (51:12) and a reminder about the Exodus (51:9-10, 15).⁴⁵ In fact, if we had to sum up the message of this oracle, we could not do much better than, 'I am; do not be afraid'!

Thus, when the saying of John 6:20 is read in the context of (a) the subsequent egō eimi sayings in John, (b) the wider parallel between Jesus' exploits over the sea in this narrative and God's exploits over the sea in the Old Testament, and (c) the prevalence of the instruction 'Do not be afraid' from God to his people in deutero-Isaiah, it is at highly plausible that John intends egō eimi here to convey the same secondary meaning that it has in chapter 8. That is, the meaning drawn from God's pronouncements of his exclusive deity in deutero-Isaiah LXX.

 4.6. John 4:26: 'I am—the one who is speaking with you'

The saying of John 4:26 occurs in the dialogue between Jesus and the Samaritan woman at the well. The woman says to Jesus, 'I know that the Messiah is coming, the one called the Anointed; when he comes, he will tell us everything.' Jesus replies, 'I am he (egō eimi), the one who is speaking with you.' As with John 6:20, this is a saying in which, on its surface, egō eimi bears only the ordinary SIA sense that it has in John 9:9 when the healed blind man says it. The woman refers to the Messiah, and Jesus says, 'I am he,' meaning 'I am the Messiah'—a theologically profound statement, to be sure, but not a claim to the attributes of deity.

Is there any reason to see a double meaning here in which egō eimi means more than this, and bears the loftier sense that it has in deutero-Isaiah? That it clearly bears this sense in John 8 at least gives this interpretation prima facie plausibility. Perhaps we can go further than conjecture, however. The key attribute of the Messiah that is emphasised both in the woman's remark ('he will tell us everything') and in Jesus' reply ('the one who is speaking with you') is speech. This emphasis relates to the Prologue of John (1:1-18), which identifies Christ as the pre-existent Word.⁴⁶ Deutero-Isaiah repeatedly emphasises God's unique identity as the One who speaks with his people and declares the truth. We now want to consider the relevance of two particular texts from deutero-Isaiah LXX that closely parallel John 4:26.

First, we have Isaiah 45:18-19 LXX: 'I am (egō eimi), and there is no other. I have not spoken in secret nor in a dark place of the earth; I did not say to the offspring of Iakob, "Seek a vain thing." I am (egō eimi), I am the Lord, speaking righteousness and declaring truth.' In this text, God twice expresses his deity using the expression egō eimi, while simultaneously emphasising his character as the one who speaks. We have already observed that the statement, 'I have not spoken in secret' is echoed by Jesus in John 18:20.⁴⁷

Second, we have Isaiah 52:6-7 LXX, where God foretells Israel's redemption, saying, 'Therefore my people shall know my name in that day, because I myself am the one who speaks: I am here, like season upon the mountains, like the feet of one bringing glad tidings of a report of peace...' As noted earlier, Isaiah 52:6 MT is an ʾ^anî hûʾ saying. Isaiah 52:6 LXX does not contain an absolute egō eimi saying, because egō eimi has a predicate, 'the one who speaks.' Nevertheless, the Greek is very close to that of John 4:26. Isaiah 52:6 LXX includes the words egō eimi autos ho lalōn, while Jesus' saying in John 4:26 is, egō eimi ho lalōn soi. The only difference is that John lacks autos ('myself'), which is merely for emphasis, and adds soi ('to you'/'with you'), to indicate that he is currently speaking with the woman. The parallels between John 4:26 and these two texts from deutero-Isaiah are close enough that, in light of the wider use of egō eimi in John, it is quite likely that the Isaianic sense of the phrase is intended here as well.

 4.7. John 18:5-8: 'When he said to them, "I am," they turned away and fell to the ground'

The last of the egō eimi sayings in John occur at the moment of Jesus' arrest in John 18:5-8. At the approach of a band of soldiers and guards, Jesus goes forth and asks, 'Whom are you looking for?' The narrative proceeds:

5 They answered him, "Jesus the Nazorean." He said to them, "I am." Judas his betrayer was also with them. 6 When he said to them, 'I am,' they turned away and fell to the ground. 7 So he again asked them, "Whom are you looking for?" They said, "Jesus the Nazorean." 8 Jesus answered, "I told you that I am. So if you are looking for me, let these men go."

As with the egō eimi sayings in John 4:26 and 6:20, it is clear that the primary sense of the phrase is SIA: Jesus is saying, 'I am he' or 'it is I,' confirming that he is Jesus the Nazorean whom they seek. However, in addition to what we have seen in the six preceding egō eimi sayings in John, there are indications that a secondary, more profound meaning of egō eimi is in view here. The first indication is that the expression is repeated three times, placing special stress upon it. The second indication is the soldiers' reaction when he first says it: 'they turned away and fell to the ground.' The verb piptō ('fall down') is often used of an act of worship.⁴⁸ Given the Fourth Evangelist's penchant for ironic actions by non-believers (cf., e.g,. John 11:49-51, 19:2-3; 19:19-22), this is surely more than just an interesting anecdote about the soldiers' surprise at Jesus' willingness to present himself for arrest. Rather, it is likely that the soldiers are ironically making the correct response to the full meaning of Jesus' self-declaration, egō eimi: they fall down in worship.

There is no verbal parallel to this saying in deutero-Isaiah. However, in light of the parallels already seen between Johannine egō eimi sayings and God's egō eimi sayings in Isaiah 45:18-19, John may see in this episode a provisional fulfillment of the words of Isaiah 45:23 LXX: 'to me every knee shall bow and every tongue shall acknowledge God.' Hence, rather than seeing in this passage merely a proactive effort by Jesus to identify himself as Jesus to the authorities, we ought to see the threefold occurrence of egō eimi as 'an emphatic climax of the series' of egō eimi sayings in John.⁴⁹

5. Christological Implications

In this series of articles, we have argued that Jesus' three egō eimi sayings in John 8 (vv. 24, 28, 58) as well as those elsewhere in the Gospel (John 4:26; 6:20; 13:19; 18:5-8) are best understood as profound Christological declarations that allude to, and draw their ultimate meaning from, the use of egō eimi in the Septuagint version of deutero-Isaiah. Accordingly, we must conclude that John understood Jesus to identify himself as the divine Word who, together with the Father, is the one God of Israel.

The series has had only limited interaction with secondary scholarship, but most of the ideas presented here are not novel. As D. A. Carson remarks, 'the majority of interpreters today' understand the egō eimi sayings of John 8 to be rooted in those of Isaiah 40-55.⁵⁰ Numerous scholars such as Richard Bauckham have made the same claim for the other egō eimi sayings in John. There is not, however, general agreement on the Christological implications of this connection. For instance, whereas Richard Bauckham asserts that the link between the Johannine egō eimi sayings and those of deutero-Isaiah mean that John's Jesus 'is unambiguously identifying himself with the one and only God, YHWH, the God of Israel' and not 'merely as an..."agent" or "emissary",'⁵¹ other scholars such as James F. McGrath see the Isaianic background as pointing to just such an 'agency' Christology. McGrath regards the egō eimi sayings as depicting Jesus as 'the bearer of the divine name,' as 'God's principal agent,' on whom was bestowed an authority equal to the sender.⁵²

What makes an 'agency' reading of the egō eimi sayings inadequate is that an agent's message is not about himself; he is a representative and spokesperson for another and his words, even when spoken in the first person, are primarily about the sender and not the agent.⁵³ Thus, under an agency Christology, Jesus' egō eimi sayings would be statements by and about the Father, conveyed to humanity by his agent, Jesus, whose own characteristics would be of secondary importance. This does not fit the context of the egō eimi sayings, which are clearly about Jesus himself (although of course Jesus is sent by the Father and is indeed his spokesperson as the Word). In John 4:26, Jesus is identifying himself as the speaker who is the Messiah. In 6:20, Jesus is identifying himself as the one they saw walking on the water, displaying divine power over the sea. In 8:24 it is Jesus himself in whom the Pharisees must believe to avoid dying in their sins. In 8:28 it is Jesus himself who will be lifted up and who does nothing on his own. In 8:58 it is Jesus who identifies himself as existing before Abraham came to be, and it is consequently Jesus that his hearers want to stone. In 13:19 it is Jesus himself who is telling the disciples events before they happen. In 18:5-8 it is, of course, Jesus who identifies himself as Jesus the Nazorean. Thus, the 'I am' sayings serve primarily to communicate truths about Jesus, implying that their lofty ontological claims (seen in light of the Isaianic background) cannot be shifted from Jesus onto the Father. This is by no means to deny that Jesus is the Father's agent; it is to understand that the Father's choice of Jesus as his agent is not arbitrary but follows from the ontological reality of who Jesus is: the divine and pre-existent Word and Son.⁵⁴ Thus, David M. Ball rightly states that

Jesus can only claim a phrase that was reserved for YHWH and apply it to himself because it is not only YHWH's Son but is in fact YHWH speaking... The connection between Jesus' use of "I am" and the Logos of the prologue again suggests that the Johannine church believed in an ontological identification of the historical person Jesus and the Jewish God.⁵⁵

Similarly, Richard Bauckham writes concerning chapters 40-55 of Isaiah, 'Their proclamation of eschatological salvation is intimately linked to their emphatic assertion of the absolute uniqueness of the God of Israel, who in these chapters constantly asserts his unique deity in contrast with the idols of the nations who are no gods, and defines his uniqueness as that of the eternal Creator of all things and the unique sovereign Ruler of all history. His great act of eschatological salvation will demonstrate him to be the one and only God in the sight of all the nations, revealing his glory so that all the ends of earth will acknowledge him as God and turn to him for salvation. All this is summed up in the divine self-declaration "I am he"' ('Monotheism and Christology in the Gospel of John', in Contours of Christology in the New Testament [ed. Richard N. Longenecker; Grand Rapids: Eerdmans, 2005], 158).

Isaiah 52:6 LXX ('Therefore my people shall know my name in that day, because I myself am the one who speaks: I am here') does have egō eimi corresponding to the MT's ʾ^anî hûʾ, but strictly speaking it is not absolute. Isaiah 45:18 and 45:19 LXX have egō eimi where the MT does not have a corresponding absolute ʾ^anî hûʾ  (45:18 does have ʾ^anî y^ehwâ, 'I am Yahweh').
• 23 In the MT, the daughter of Babylon does not say ʾ^anî hûʾ but merely ʾ^anî. See a similar usage in Zeph. 2:15 LXX.

• 25 Williams notes, 'The renderings principally favoured by the Septuagint (ἐγώ εἰμι) and the Vulgate (ego ipse) clearly seek to maintain the bipartite character of אני הוא in its role as a claim to uniqueness' (I Am He, 304).
• 26 Similarly, 2 Kingdoms 2:20 LXX: 'And Abenner looked behind him and said, "Are you Asael himself?" And he answered, "I am" (egō eimi).'
• 27 Jesus identifying himself in an epiphanic setting: Matt. 14:27, Mark 6:50, Luke 24:39. In this article we will leave open the question of whether these Synoptic sayings may already allude to the divine egō eimi formula of deutero-Isaiah. Jesus responds affirmatively to the question of whether he is the Messiah in Mark 14:62 with 'I am' (egō eimi) and in Luke 22:70 with 'You say that I am.' In the Olivet discourse, Jesus foretells of Messianic pretenders 'coming in my name' and saying, 'I am' (egō eimi, Mark 13:6; Luke 21:8; Matt. 24:5 has egō eimi ho Christos, 'I am the Messiah'). Finally, Acts 13:25 has John the Baptist confessing, 'I am not he' (ouk egō eimi).
• 28 This parallel was not explored in Part 2. In John 8:23, Jesus tells the Pharisees, 'You belong to what is below, I belong to what is above. You belong to this world, but I do not belong to this world.' This parallels Isaiah 41:24 LXX, where God enters into judgment with men and declares, 'Because whence are you and whence is your work? From the earth.' Similarly, Isaiah 55:9 LXX contrasts God's ways with men's ways using the analogy of heaven's distance from earth: 'But as heaven is far from the earth, so is my way far from your ways and your notions from my thought.'
• 29 Of course, Jesus is not making an exclusive claim to deity that excludes the Father. As he consistently points out throughout this Gospel whenever making lofty claims about himself, he is not independent of the Father but is his beloved Son, who was sent by him, who obeys him, who does nothing without him (John 8:28-29).
• 30 Briefly, it has strong resonances with the Word in John 1:1-3, since the speaker emphasises his 'speaking' function from the beginning, and contrasts an imperfect form of eimi ('be') with an aorist form of ginomai ('come to be' or 'become'). As was noted previously, the statement in Isaiah 48:16 that 'I have not spoken in secret' parallels Jesus' statement before the high priest in John 18:20.
• 31 In the soliloquy of Lady Wisdom in Proverbs 8:22-25 LXX, Wisdom describes herself as having been created, but 'as the beginning of his ways...before the present age...in the beginning...before he made the earth.' Significantly, while 'the Lord created me' (kurios ektisen me) uses an aorist verb, the subsequent statement 'before all the hills he begets me' is in present tense (genna me). In Job 38, the Lord speaks to Job through a whirlwind and contrasts at great length his own eternity and power with the puny existence of Job. In Psalm 109:3 LXX (110:3 Eng), one is addressed with the words, 'From the womb, before Morning-star, I brought you forth.' This psalm (esp. vv. 1, 4) played a very important role in earliest Christology, and Aquila H. I. Lee has argued in a monograph that v. 3 was pivotal in the development of a belief in the pre-existence of Christ in the pre-Pauline church (From Messiah to Preexistent Son: Jesus' Self-Consciousness and Early Christian Exegesis of Messianic Psalms [Tübingen: Mohr Siebeck, 2005]). Finally, Sirach 42:21 says of God, 'since he is before the age and forever' (my translation); the Greek is close to that of, and may be dependent on, Psalm 89:2.
• 32 Both texts have hina pisteusēte...hoti egō eimi. We noted in Part 2 that this is a special case of a very common Old Testament formula by which God foretells that when some future event happens, his people will or may know/believe that he is their God. John contains frequent adaptations of this formula, with Jesus being the object in most instances.
• 33 'As for the things that were from the beginning, see, they have come; also new things, which I myself will declare, and before they sprang forth, they were made plain to you' (Isa. 42:9); 'Who is like me? Let him stand; let him call, and let him make ready for me, inasmuch as I have made man forever, and let them declare to you the things that are coming before they come' (Isa. 44:7); 'because I am God, and there is no other besides me, declaring the last things first, before they happen, and at once they came to pass' (Isa. 46:9-10); 'The former things I have moreover declared, and they went out from my mouth and came to be heard; suddenly I did them, and they came to pass... I declared to you the things of old; before they came upon you I made them to be heard by you; do not say, "The idols did them for me"' (Isa. 48:3, 5).
• 34 I do not discount the possibility of a secondary, epiphanic meaning in Matthew and Mark, for the same Old Testament contextual reasons about to be discussed, but it is beyond the scope of this article to argue the point.
• 35 This is assuming, with most scholars, that Mark predates John by at least a couple of decades. I am not implying that the Fourth Evangelist fabricated the other egō eimi sayings. However, if one takes the view that Jesus' discourses in John at least reflect significant editorial work by the author, one possible explanation for the egō eimi sayings is that John received some of them in his source material (certainly John 6:20, and possibly 4:26 and 18:5-8). Understanding egō eimi in these sayings to convey a double meaning (informed by his reading of deutero-Isaiah LXX), he then adapted other sayings of Jesus—which may or may not have already used egō eimi—to more clearly convey the double meaning. The result is the sayings in John 8:24, 28, 58 and 13:19. This is merely a conjecture; it is also entirely possible that the double meaning of egō eimi was well-developed already in the earliest stratum of the Signs source. Note the comment of James D. G. Dunn, who writes, 'Again, it is possible to see a Synoptic-type root for the weighty "I am" sayings – Mark 6:50, 13:6, 14:62; but again the indications are clear and strong that the weightier Johannine sayings are a development from the earlier tradition at best tangential to the earlier tradition. For the Markan ‘I am’ sayings are simply affirmative utterances (It’s me, I am he, Yes), as Matthew clearly indicates (Matt. 24:5; 26:64). But John has probably seen a potential link with the "I am" of Isa. 43:10 and exploited it accordingly (especially John 8:24, 28, 58; 13:19). It is surely scarcely credible that a saying like John 8:58, or the other "I am" sayings (the bread of life, the light of the world, etc.) were part of the earliest Jesus-tradition, and yet nothing approaching them appears in the Synoptic Gospels. Why should they be so completely neglected if part of the authentic sayings of Jesus, and why should only John preserve them? The most obvious explanation once again is that in a relatively insignificant element of the earlier tradition John has found the inspiration to fashion an invaluable formula for expressing Christianity’s claims about Christ' (Christology in the Making: A New Testament Inquiry into the Origins of the Doctrine of the Incarnation [2nd edn; London: SCM Press, 1989], 30-31).

Awake, as at the beginning of a day, like a generation of long ago! Are you not 10 she who made desolate the sea, the water, the abundance of the deep, who made the depths of the sea a way of passage for those being delivered 11 and those who have been ransomed? For by the Lord they shall be returned and come to Sion with joy and everlasting gladness; for gladness and praise shall be upon their heads and joy shall take hold of them; pain and sorrow and sighing have fled away. 12 I am (egō eimi), I am he who comforts you. Acknowledge of whom you were cautious; you were afraid because of a mortal man and a son of man, who have dried up like grass. 13 And you have forgotten God who made you, who made heaven and laid the foundations of the earth. And always, all the days, you feared the face of the fury of the one who was oppressing you, for just as he planned to do away with you, and where now is the fury of the one who was oppressing you? 14 For when you are saved, he will not stand nor linger, 15 because I am your God, who stirs up the sea and makes its waves to sound—the Lord Sabaoth is my name.
• 46 This emphasis on Jesus as speaker, reflecting his character as the Word, is also present in sayings such as John 3:34, 6:63, 9:37.
• 47 As noted previously, this parallels not only Isaiah 45:19 LXX but also 48:16 LXX, where the speaker is the mysterious figure who has existed from the beginning and has been sent by the Lord and his spirit.

• 52 'When examined carefully, the Johannine ‘I am’ sayings do not appear to represent a direct assertion that Jesus is none other than the God of the Jewish Scriptures, so much as an allusive indication that he bears the divine name. Similar claims had been made for other figures in at least some Jewish circles, although nothing in the extant parallels is quite as extravagant as what we find in John. Nevertheless, when one considers the statement by the angel in Apoc. Abr. 10:8, ‘I am Yaoel’, in light of the application of the very same name to God in Apoc. Abr. 17:13, one can see how easily the statement of the angel could have been regarded by some as blasphemous, and misconstrued as a claim to be God himself. But this use of the divine name by the angel does not represent a claim to be the God of the Old Testament, but to be the special, unique agent of God. The figure who bears the name of God does so as part of his empowering and commissioning as God’s principal agent, and, as we have already seen, agency bestowed an equality of authority to, coupled with a complete submission to, the sender... [Thus it appears likely that] the Johannine "I am" represents something rather subtler and more carefully nuanced than this: it portrays Jesus as the bearer of the divine name, the agent upon whom God has bestowed his name.' (John's Apologetic Christology: Legitimation and Development in Johannine Christology [Cambridge: Cambridge University Press, 2004], 105-106.)
• 53 For instance, if we consider the message of the angel Yaoel to Abraham in Apocalypse of Abraham 10 (the text cited by McGrath in support of the kind of agency he sees in Jesus' 'I am' sayings), the message is primarily about God and not Yaoel.
• 54 Probably the key Isaianic text on this point, as already discussed, is 48:16 LXX, where the pre-existent speaker describes himself as sent by the Lord and his spirit.
