Crassus next came with Roman troops into Judea and pillaged the Temple, and then marched into Parthia, where both he and his army perished. Then Cassius obtained Syria, and checked the Parthians. He passed on to Judea, fell on Tarichæa, and took it, and carried away 3,000 Jewish captives. A wealthy Idumean named Antipater, who had been a great friend of Hyrcanus, and had helped him against Aristobulus, was a very active and seditious man. He had married Cypros, a lady of his own Idumean race, by whom he had four sons, Phaselus, and Herod, who afterwards became king, and Joseph, and Pheroras; and a daughter, Salome. He cultivated friendship with other potentates, especially with the King of Arabia, to whom he committed the care of his children while he fought against Aristobulus. But when Cæsar had taken Rome, and after Pompey and the senate had fled beyond the Ionian Sea, Aristobulus was set free from the bonds in which he had been laid. Cæsar resolved to send him with two legions into Syria to set matters right; but Aristobulus had no enjoyment of this trust, for he was poisoned by Pompey's party. But Scipio, sent by Pompey to slay Alexander, son of Aristobulus, cut off his head at Antioch. And Ptolemy, son of Menneus, ruler of Chalcis, took Alexander's brethren to him, and sent his son Philippion to Askelon to Aristobulus's wife, and desired her to send back with him her son Antigonus and her daughters; the one of whom, Alexandra, Philippion fell in love with, and married her; though afterwards his father Ptolemy slew him, and married Alexandra. Now, after Pompey was dead, and after the victory Cæsar had gained over him, Antipater, who had managed the Jewish affairs, became very useful to Cæsar when he made war against Egypt, and that by the order of Hyrcanus. He brought over to the side of Cæsar the principal men of the Arabians, and also Jamblicus, the ruler of the Syrians, and Ptolemy, his son, and Tholomy, the son of Sohemus, who dwelt at Mount Libanus, and almost all the cities, and with 3,000 armed Jews he joined Mithradates of Pergamus, who was marching with his auxiliaries to aid Cæsar. Antipater and Mithradates together won a pitched battle against the Egyptians, and Cæsar not only then commended Antipater, but used him throughout that war in the most hazardous undertakings, and finally, at the end of that campaign, made him procurator of Judea, at the same time appointing Hyrcanus high-priest. Antipater, seeing that Hyrcanus was of a slow and slothful temper, made his eldest son, Phaselus, governor of Jerusalem; but committed Galilee to his next son, Herod, who was only fifteen, but was a youth of great mind, and soon proved his courage, and won the love of the Syrians by freeing their country of a nest of robbers, and slaying the captain of these, one Hezekias.
