ISB ~ Mark 6 v14

King Herod:Herod Antipas. After the death of Herod the Great (4/1 B.C.), the Roman Emperor Augustus divided the kingdom in Palestine among three of Herod’s sons. Herod Antipas was the son who received the title “tetrarch” (Mt 14:1) and governed the regions of Galilee and Perea until A.D. 39. His brothers Archelaus and Philip were apportioned the remainder of their late father’s territory. Since “tetrarch” is not strictly a royal title, the use of “King” here probably reflects popular usage and is not intended literally (Mt 14:9).
