[190] Thus was Pelusium taken. But still, as they were marching on, those Egyptian Jews that inhabited the country called the country of Onias stopped them. Then did Antipater not only persuade them not to stop them, but to afford provisions for their army; on which account even the people about Memphis would not fight against them, but of their own accord joined Mithridates. Whereupon he went round about Delta, and fought the rest of the Egyptians at a place called the Jews' Camp; nay, when he was in danger in the battle with all his right wing, Antipater wheeled about, and came along the bank of the river to him; for he had beaten those that opposed him as he led the left wing. After which success he fell upon those that pursued Mithridates, and slew a great many of them, and pursued the remainder so far that he took their camp, while he lost no more than fourscore of his own men; as Mithridates lost, during the pursuit that was made after him, about eight hundred. He was also himself saved unexpectedly, and became an unreproachable witness to Caesar of the great actions of Antipater.
