Footnotes:

1. John 1:40 tn Grk “who heard from John.”
2. John 1:40 tn Grk “him”; the referent (Jesus) has been specified in the translation for clarity.
3. John 1:41 tc Most witnesses (א* L W^s M) read πρῶτος (prōtos) here instead of πρῶτον (prōton). The former reading would be a predicate adjective and suggest that Andrew “was the first” person to proselytize another regarding Jesus. The reading preferred, however, is the neuter πρῶτον, used as an adverb (BDAG 893 s.v. πρῶτος 1.a.β.), and it suggests that the first thing that Andrew did was to proselytize Peter. The evidence for this reading is early and weighty: P^66,75 א² A B Θ Ψ 083 ƒ^1,13 892 al lat.
4. John 1:41 sn Naturally part of Andrew’s concept of the Messiah would have been learned from John the Baptist (v. 40). However, there were a number of different messianic expectations in 1st century Palestine (see the note on “Who are you?” in v. 19), and it would be wrong to assume that what Andrew meant here is the same thing the author means in the purpose statement at the end of the Fourth Gospel, 20:31. The issue here is not whether the disciples’ initial faith in Jesus as Messiah was genuine or not, but whether their concept of who Jesus was grew and developed progressively as they spent time following him, until finally after his resurrection it is affirmed in the climactic statement of John’s Gospel, the affirmation of Thomas in 20:28.
5. John 1:41 tn Both Greek “Christ” and Hebrew and Aramaic “Messiah” mean “the one who has been anointed.”sn This is a parenthetical note by the author. See the note on Christ in 1:20.
6. John 1:42 tn Grk “He brought him”; both referents (Andrew, Simon) have been specified in the translation for clarity.
7. John 1:42 tc The reading “Simon, son of John” is well attested in P^66,75,106 א B* L 33 it co. The majority of mss (A B² Ψ ƒ^1,13 M) read “Simon, the son of Jonah” here instead, but that is perhaps an assimilation to Matt 16:17.
8. John 1:42 sn This is a parenthetical note by the author. Giving Simon the name of Cephas is indicative of the future role he will play. Only John among the gospel writers gives the Greek transliteration (Κηφᾶς, Kēphas) of Simon’s new name, Qéphâ (which is Galilean Aramaic). Neither Πέτρος (Petros) in Greek nor Qéphâ in Aramaic is a normal proper name; it is more like a nickname.
