Flavius Josephus, Antiquities of the Jews
William Whiston, A.M., Ed.

[270] WHEN Antiochus had taken the kingdom, he was afraid to make war against Judea, because he heard that his brother by the same mother, who was also called Antiochus, was raising an army against him out of Cyzicum; so he staid in his own land, and resolved to prepare himself for the attack he expected from his brother, who was called Cyzicenus, because he had been brought up in that city. He was the son of Antiochus that was called Soter, who died in Parthia. He was the brother of Demetrius, the father of Grypus; for it had so happened, that one and the same Cleopatra was married to two who were brethren, as we have related elsewhere. But Antiochus Cyzicenus coming into Syria, continued many years at war with his brother. Now Hyrcanus lived all this while in peace; for after the death of Antlochus, he revolted from the Macedonians, ¹ nor did he any longer pay them the least regard, either as their subject or their friend; but his affairs were in a very improving and flourishing condition in the times of Alexander Zebina, and especially under these brethren, for the war which they had with one another gave Hyrcanus the opportunity of enjoying himself in Judea quietly, insomuch that he got an immense quantity of money. How ever, when Antiochus Cyzicenus distressed his land, he then openly showed what he meant. And when he saw that Antiochus was destitute of Egyptian auxiliaries, and that both he and his brother were in an ill condition in the struggles they had one with another, he despised them both.
