Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 3:1-2

“Through the whole of the time until his shewing himself he was hid in the wilderness, that no suspicion might arise in men’s minds, that from his relation to Christ, and from his intercourse with Him from a child, he would testify such things of Him; and hence he said, I knew him not. (John 1:33.)”
