But the imprisoned Aristobulus looked forward once again to the hope of placing himself upon his father's throne and of banishing Antipater into obscurity. Julius Cæsar, the greatest man that Rome ever produced, had openly defied the Senate, and broken with his associate Pompey. The bitter strife between the two Roman potentates lit the torch of war in the most distant provinces of the Roman empire. Cæsar had given Aristobulus his freedom, and in order to weaken Pompey's influence, had sent him with two legions to Palestine to create a diversion in his favor. But the partisans of Pompey contrived to poison the Judæan prince. His followers embalmed his body in honey and carried it to Jerusalem, where it was buried beside the bodies of the Hasmonæan princes. His eldest son, the gallant Alexander, was decapitated by order of Scipio, a follower of Pompey, at Antioch. The widow of Aristobulus and his surviving son Antigonus found protection with Ptolemy, prince of Chalcis, whose son Philippion had fallen in love with Alexandra, the daughter of Aristobulus, and had brought her to his father's court. But Ptolemy, out of criminal love to his own daughter-in-law, caused his son to be murdered and married the widow. Antipater continued to be Pompey's faithful ally, until the Roman general met with a miserable end in Egypt. Then the Idumæan offered his services to Cæsar. When the great general found himself in Egypt, without sufficient forces, without news from Rome, in the midst of a hostile population, Antipater evinced a touching eagerness to help him, which did not remain unrewarded. He provided the army of Cæsar's ally, Mithridates, king of Pergamus, with all necessaries, and sent him a contingent of Judæan troops; he aided him in conquering Pelusium, and conciliated the Egyptian-Judæans who had taken the part of his opponent. He was now well able to forego the favor of Hyrcanus. To no effect did Antigonus, the last surviving son of Aristobulus, seek an interview with Cæsar, in which he dwelt upon his father's and his brother's loyalty to the Roman general; Antipater had but to display his wounds, which he had received in the very last campaign, to gain the victory over his rival. Cæsar, who was an astute reader of men, and who had himself revolted from the legitimate order of things, knew well enough how to value Antipater's loyalty and energy, and did not support the rightful claims of Antigonus. Out of consideration for Antipater (47), Hyrcanus was proclaimed high priest and ethnarch, and to Judæa was given some relief from her burdens. The walls of Jerusalem were rebuilt, the provinces that formerly belonged to Judæa, namely, Galilee, the towns in the plains of Jezreel, and Lydda, were once more made part of her territory. The Judæans were no longer forced to provide winter quarters for the Roman legions, although the landowners were obliged to give the fourth part of their harvest every second year to the Roman troops.
