At that time Herod the tetrarch,.... Not Herod the Great, in whose reign Christ was born, and who slew the infants of Bethlehem, but his son; this was, as the Jewish chronologer rightly observes,"Herod Antipater, whom they call yqrtyj, "the tetrarch"; the son of Herod the First, and brother of Archelaus, and the third king of the family of Herod.'
'And though he is here called a "tetrarch", he is in Mr 6:14 called a king: the reason of his being styled a "tetrarch" was this; his father Herod divided his large kingdom into four parts, and bequeathed them to his sons, which was confirmed by the Roman senate: Archelaus reigned in Judea in his stead; upon whose decease, that part was put under the care of a Roman governor; who, when John the Baptist began to preach, was Pontius Pilate; this same Herod here spoken of, being "tetrarch" of Galilee, which was the part assigned him; and his brother Philip "tetrarch" of Ituraea, and of the region of Trachonitis; and Lysanias, "tetrarch" of Abilene, Lu 3:1 the word "tetrarch": signifying one that has the "fourth" part of government: and in Munster's Hebrew Gospel, he is called "one of the four princes"; and in the Arabic version, "a prince of the fourth part"; and in the Persic, a "governor of the fourth part of the kingdom".
The "time" referred to, was after the death of John the Baptist; and when Christ had been for a good while, and in many places, preaching and working miracles; the particular instant which respect is had unto, is the sending forth of the twelve disciples to preach and work miracles; and which might serve the more to spread the fame of Christ, and which reached the court of Herod; who, it is said here,heard of the fame of Jesus: what a wonderful preacher he was, and what mighty things were done by him.
