New Defender's Study Bible Notes
14:1 Herod the tetrarch. This Herod was Herod Antipas, son of Herod the Great, who had been king when Jesus was born. He was made tetrarch of Galilee, while his brother Archelaus was ruling as ethnarch over Judea (Matthew 2:22), the province in which both Jerusalem and Bethlehem were located. Another son, Philip, had been made tetrarch of Iturea (Luke 3:1).
