John 12:36

ὡς τ. φῶς ἔχετε. As ye have the Light (as in John 12:35), believe on the Light, that ye may become sons of light. Note the impressive repetition of φῶς (comp. John 1:10; John 3:17; John 3:31; John 15:19; John 17:14), and the absence of the article before φωτός. In all the four preceding cases τὸ φῶς means Christ, as in John 1:5; John 1:7-9. The expression ‘child of’ or ‘son of’ is frequent in Hebrew to indicate very close connexion as between product and producer (see on John 17:12): υἱὸς εἰρήνης, Luke 10:6; οἱ υἱοὶ τ. αἰῶνος τούτου, John 16:8; υἱοὶ βροντῆς, Mark 3:17. Such expressions are very frequent in the most Hebraistic of the Gospels; Matthew 5:9; Matthew 8:12; Matthew 9:15; Matthew 13:38; Matthew 23:15.

ταῦτα ἐλάλησεν. He gave them no other answer, departed, and did not return. S. John is silent as to the place of retirement, which was probably Bethany (Matthew 21:17; Mark 11:11; Luke 21:37). The one point which he would make prominent is the Christ’s withdrawal from His people. Their time of probation is over. They have closed their eyes again and again to the Light; and now the Light itself is gone. He was hidden from them.
