At this point Herod appears on the scene as ruler of Galilee (Jos. _Ant._ xiv. 9. 2) appointed by his father at the age of fifteen or, since he died at seventy, twenty-five. In spite of his youth he soon found an opportunity of displaying his mettle; for he arrested Hezekiah the arch-brigand, who had overrun the Syrian border, and put him to death. The Jewish nobility at Jerusalem seized upon this high-handed action as a pretext for satisfying their jealousy of their Idumaean rulers. Herod was cited in the name of Hyrcanus to appear before the Sanhedrin, whose prerogative he had usurped in executing Hezekiah. He appeared with a bodyguard, and the Sanhedrin was overawed. Only Sameas, a Pharisee, dared to insist upon the legal verdict of condemnation. But the governor of Syria had sent a demand for Herod's acquittal, and so Hyrcanus adjourned the trial and persuaded the accused to abscond. Herod returned with an army, but his father prevailed upon him to depart to Galilee without wreaking his vengeance upon his enemies. About this time (47-46 B.C.) he was created _strategus_ of Coelesyria by the provincial governor. The episode is important for the light which it throws upon Herod's relations with Rome and with the Jews. In 44 B.C. Cassius arrived in Syria for the purpose of filling his war-chest: Antipater and Herod collected the sum of money at which the Jews of Palestine had been assessed. In 43 B.C. Antipater was poisoned at the instigation of one Malichus, who was perhaps a Jewish patriot animated by hatred of the Herods and their Roman patrons. With the connivance of Cassius Herod had Malichus assassinated; but the country was in a state of anarchy, thanks to the extortions of Cassius and the encroachments of neighbouring powers. Antony, who became master of the East after Philippi, was ready to support the sons of his friend Antipater; but he was absent in Egypt when the Parthians invaded Palestine to restore Antigonus to the throne of his father Aristobulus (40 B.C.). Herod escaped to Rome: the Arabians, his mother's people, had repudiated him. Antony had made him tetrarch, and now with the assent of Octavian persuaded the Senate to declare him king of Judaea. In 39 B.C. Herod returned to Palestine and, when the presence of Antony put the reluctant Roman troops entirely at his disposal, he was able to lay siege to Jerusalem two years later. Secure of the support of Rome he was concerned also to legitimize his position in the eyes of the Jews by taking, for love as well as policy, the Hasmonaean princess Mariamne to be his second wife. Jerusalem was taken by storm; the Roman troops withdrew to behead Antigonus the usurper at Antioch. In 37 B.C. Herod was king of Judaea, being the client of Antony and the husband of Mariamne.
