[342] So both Hyrcanus and Phasaelus went on the embassage; but Pacorus left with Herod two hundred horsemen, and ten men, who were called the freemen, and conducted the others on their journey; and when they were in Galilee, the governors of the cities there met them in their arms. Barzaphanles also received them at the first with cheerfulness, and made them presents, though he afterward conspired against them; and Phasaelus, with his horsemen, were conducted to the sea-side. But when they heard that Antigonus had promised to give the Parthians a thousand talents, and five hundred women, to assist him against them, they soon had a suspicion of the barbarians. Moreover, there was one who informed them that snares were laid for them by night, while a guard came about them secretly; and they had then been seized upon, had not they waited for the seizure of Herod by the Parthians that were about Jerusalem, lest, upon the slaughter of Hyrcanus and Phasaelus, he should have an intimation of it, and escape out of their hands. And these were the circumstances they were now in; and they saw who they were that guarded them. Some persons indeed would have persuaded Phasaelus to fly away immediately on horseback, and not stay any longer; and there was one Ophellius, who, above all the rest, was earnest with him to do so; for he had heard of this treachery from Saramalla, the richest of all the Syrians at that time, who also promised to provide him ships to carry him off; for the sea was just by them. But he had no mind to desert Hyrcanus, nor bring his brother into danger; but he went to Barzapharnes, and told him he did not act justly when he made such a contrivance against them; for that if he wanted money, he would give him more than Antigonus; and besides, that it was a horrible thing to slay those that came to him upon the security of their oaths, and that when they had done them no injury. But the barbarian swore to him that there was no truth in any of his suspicions, but that he was troubled with nothing but false proposals, and then went away to Pacorus.
