[137] SO Claudius sent Felix, the brother of Pallas, to take care of the affairs of Judea; and when he had already completed the twelfth year of his reign, he bestowed upon Agrippa the tetrarchy of Philip and Batanea, and added thereto Trachonites, with Abila; which last had been the tetrarchy of Lysanias; but he took from him Chalcis, when he had been governor thereof four years. And when Agrippa had received these countries as the gift of Caesar, he gave his sister Drusilla in marriage to Azizus, king of Emesa, upon his consent to be circumcised; for Epiphanes, the son of king Antiochus, had refused to marry her, because, after he had promised her father formerly to come over to the Jewish religion, he would not now perform that promise. He also gave Mariamne in marriage to Archelaus, the son of Helcias, to whom she had formerly been betrothed by Agrippa her father; from which marriage was derived a daughter, whose name was Bernice.
