[13:30] 1 tn Grk “That one”; the referent (Judas) has been specified in the translation for clarity.
[13:30] 2 sn Now it was night is a parenthetical note by the author. The comment is more than just a time indicator, however. With the departure of Judas to set in motion the betrayal, arrest, trials, crucifixion, and death of Jesus, daytime is over and night has come (see John 9:5; 11:9-10; 12:35-36). Judas had become one of those who walked by night and stumbled, because the light was not in him (11:10).
[13:32] 3 tc A number of early mss (Ì66 א* B C* D L W al as well as several versional witnesses) do not have the words “If God is glorified in him,” while the majority of mss have the clause (so א2 A C2 Θ Ψ Ë13 33 Ï lat). Although the mss that omit the words are significantly better witnesses, the omission may have occurred because of an error of sight due to homoioteleuton (v. 31 ends in ἐν αὐτῷ [en autw, “in him”], as does this clause). Further, the typical step-parallelism found in John is retained if the clause is kept intact (TCGNT 205-6). At the same time, it is difficult to explain how such a wide variety of witnesses would have accidentally deleted this clause, and arguments for intentional deletion are not particularly convincing. NA27 rightly places the words in brackets, indicating doubt as to their authenticity.
[13:32] 4 tn Or “immediately.”
