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

[317] By this time (the Parthians being already driven out of the country, and Pacorus slain) Ventidius, by Antony's command, sent a thousand horsemen, and two legions, as auxiliaries to Herod, against Antigonus. Now Antigonus besought Macheras, who was their general, by letter, to come to his assistance, and made a great many mournful complaints about Herod's violence, and about the injuries he did to the kingdom; and promised to give him money for such his assistance; but he complied not with his invitation to betray his trust, for he did not contemn him that sent him, especially while Herod gave him more money [than the other offered]. So he pretended friendship to Antigonus, but came as a spy to discover his affairs; although he did not herein comply with Herod, who dissuaded him from so doing. But Antigonus perceived what his intentions were beforehand, and excluded him out of the city, and defended himself against him as against an enemy, from the walls; till Macheras was ashamed of what he had done, and retired to Emmaus to Herod; and as he was in a rage at his disappointment, he slew all the Jews whom he met with, without sparing those that were for Herod, but using them all as if they were for Antigonus.
