Luke 3:19

See in St. Mark vi. 17. The wife of his brother (Philip.) The Greek adds the name, and he is also named in St. Mark; but he is a different person from the tetrarch, mentioned in chap. iii. ver. 1. (Bible de Vence) --- It was not at this time that John [the Baptist] was cast into prison; but, as St. John [the evangelist] relates, after our Saviour had begun to work miracles, and after his baptism. St. Luke anticipates this event, in order to describe more strongly the malice of Herod; who, whilst he saw multitudes flocking to hear the words of John, his own soldiers believing, and all the people receiving baptism, still could despise the Baptist, could imprison him, and put him to death. (Ven. Bede)
