¹ tn Grk “Then again Jesus spoke to them saying.”

² sn The theory proposed by F. J. A. Hort (The New Testament in the Original Greek, vol. 2, Introduction; Appendix, 87-88), that the backdrop of 8:12 is the lighting of the candelabra in the court of women, may offer a plausible setting to the proclamation by Jesus that he is the light of the world. The last time that Jesus spoke in the narrative (assuming 7:53-8:11 is not part of the original text, as the textual evidence suggests) is in 7:38, where he was speaking to a crowd of pilgrims in the temple area. This is where he is found in the present verse, and he may be addressing the crowd again. Jesus’ remark has to be seen in view of both the prologue (John 1:4, 5) and the end of the discourse with Nicodemus (John 3:19-21). The coming of Jesus into the world provokes judgment: A choosing up of sides becomes necessary. The one who comes to the light, that is, who follows Jesus, will not walk in the darkness. The one who refuses to come, will walk in the darkness. In this contrast, there are only two alternatives. So it is with a person’s decision about Jesus. Furthermore, this serves as in implicit indictment of Jesus’ opponents, who still walk in the darkness, because they refuse to come to him. This sets up the contrast in chap. 9 between the man born blind, who receives both physical and spiritual sight, and the Pharisees (John 9:13, 15, 16) who have physical sight but remain in spiritual darkness.

³ tn The double negative οὐ μή (ou mh) is emphatic in 1st century Hellenistic Greek.

⁴ tn Grk “Jesus said to them.”

⁵ tc The first person pronoun μου (mou, “my”) may be implied, especially if ὑμῶν (Jumwn, “your”) follows the second mention of “father” in this verse (as it does in the majority of mss); no doubt this implication gave rise to the reading μου found in most witnesses (א D Θ Ψ 0250 Ë^1,13 33 Ï it sy). No pronoun here is read by Ì^66,75 B C L 070 pc. This problem cannot be isolated from the second in the verse, however. See that discussion below.

⁶ tn Grk “The things which I have seen with the Father I speak about.”

⁷ tn Grk “and you.”

⁸ tc A few significant witnesses lack ὑμῶν (Jumwn, “your”) here (Ì^66,75 B L W 070 pc), while the majority have the pronoun (א C D Θ Ψ 0250 Ë^1,13 33 565 892 Ï al lat sy). However, these mss do not agree on the placement of the pronoun: τοῦ πατρὸς ὑμῶν ποιεῖτε (tou patro" Jumwn poieite), τῷ πατρὶ ὑμῶν (tw patri Jumwn), and τῷ πατρὶ ὑμῶν ταῦτα (tw patri Jumwn tauta) all occur. If the pronoun is read, then the devil is in view and the text should be translated as “you are practicing the things you have heard from your father.” If it is not read, then the same Father mentioned in the first part of the verse is in view. In this case, ποιεῖτε should be taken as an imperative: “you [must] practice the things you have heard from the Father.” The omission is decidedly the harder reading, both because the contrast between God and the devil is now delayed until v. 41, and because ποιεῖτε could be read as an indicative, especially since the two clauses are joined by καί (kai, “and”). Thus, the pronoun looks to be a motivated reading. In light of the better external and internal evidence the omission is preferred.

⁹ tn Grk “Truly, truly, I say to you.”

¹⁰ tn Grk “If anyone keeps.”

¹¹ tn Grk “my word.”

¹² tn Grk “he will never see death forever.” The Greek negative here is emphatic.

sn Those who keep Jesus’ words will not see death because they have already passed from death to life (cf. 5:24). In Johannine theology eternal life begins in the present rather than in the world to come.

¹³ tn Grk “Truly, truly, I say to you.”

¹⁴ tn Grk “before Abraham was.”

¹⁵ sn I am! is an explicit claim to deity. Although each occurrence of the phrase “I am” in the Fourth Gospel needs to be examined individually in context to see if an association with Exod 3:14 is present, it seems clear that this is the case here (as the response of the Jewish authorities in the following verse shows).
