John 7:15
Context7:15 Then the Jewish leaders 1 were astonished 2 and said, “How does this man know so much when he has never had formal instruction?” 3
John 6:45
Context6:45 It is written in the prophets, ‘And they will all be taught by God.’ 4 Everyone who hears and learns from the Father 5 comes to me.


[7:15] 1 tn Or “the Jewish authorities”; Grk “the Jews.” Here the phrase refers to the Jewish authorities or leaders who were Jesus’ primary opponents. See the note on the phrase “the Jewish leaders” in v. 1.
[7:15] 2 tn Or “began to be astonished.” This imperfect verb could also be translated ingressively (“began to be astonished”), but for English stylistic reasons it is rendered as a simple past.
[7:15] 3 tn Grk “How does this man know learning since he has not been taught?” The implication here is not that Jesus never went to school (in all probability he did attend a local synagogue school while a youth), but that he was not the disciple of a particular rabbi and had not had formal or advanced instruction under a recognized rabbi (compare Acts 4:13 where a similar charge is made against Peter and John; see also Paul’s comment in Acts 22:3).
