[14] Since therefore Antipater saw that Hyrcanus did not attend to what he said, he never ceased, day by day, to charge reigned crimes upon Aristobulus, and to calumniate him before him, as if he had a mind to kill him; and so, by urging him perpetually, he advised him, and persuaded him to fly to Aretas, the king of Arabia; and promised, that if he would comply with his advice, he would also himself assist him and go with him]. When Hyrcanus heard this, he said that it was for his advantage to fly away to Aretas. Now Arabia is a country that borders upon Judea. However, Hyrcanus sent Antipater first to the king of Arabia, in order to receive assurances from him, that when he should come in the manner of a supplicant to him, he would not deliver him up to his enemies. So Antipater having received such assurances, returned to Hyrcanus to Jerusalem. A while afterward he took Hyrcanus, and stole out of the city by night, and went a great journey, and came and brought him to the city called Petra, where the palace of Aretas was; and as he was a very familiar friend of that king, he persuaded him to bring back Hyrcanus into Judea, and this persuasion he continued every day without any intermission. He also proposed to make him presents on that account. At length he prevailed with Aretas in his suit. Moreover, Hyrcanus promised him, that when he had been brought thither, and had received his kingdom, he would restore that country, and those twelve cities which his father Alexander had taken from the Arabians, which were these, Medaba, Naballo, Libias, Tharabasa, Agala, Athone, Zoar, Orone, Marissa, Rudda, Lussa, and Oruba.
