John 12:36
Believe in the light (pisteuete eiv to fwv). That is, "believe in me as the Messiah" (John 8:12; John 9:5).
That ye may become sons of light (ina uioi fwtov genhsqe). Purpose clause with ina and second aorist subject of ginomai, to become. They were not "sons of light," a Hebrew idiom (cf. John 17:12; Luke 16:8 with the contrast), an idiom used by Paul in I Thessalonians 5:5; Ephesians 5:8. It is equivalent to "enlightened men" (Bernard) and Jesus called his disciples the light of the world (Matthew 5:14).
Hid himself from them (ekrubh ap autwn). Second aorist passive indicative of kruptw, late form (in LXX) for old ekrufh, "was hidden from them," as in John 8:59. This part of verse John 12:36 begins a new paragraph.
