[93] On the next day Varus and the king sat together in judgment, and both their friends were also called in, as also the king's relations, with his sister Salome, and as many as could discover any thing, and such as had been tortured; and besides these, some slaves of Antipater's mother, who were taken up a little before Antipater's coming, and brought with them a written letter, the sum of which was this: That he should not come back, because all was come to his father's knowledge; and that Caesar was the only refuge he had left to prevent both his and her delivery into his father's hands. Then did Antipater fall down at his father's feet, and besought him not to prejudge his cause, but that he might be first heard by his father, and that his father would keep himself unprejudiced. So Herod ordered him to be brought into the midst, and then lamented himself about his children, from whom he had suffered such great misfortunes; and because Antipater fell upon him in his old age. He also reckoned up what maintenance and what education he had given them; and what seasonable supplies of wealth he had afforded them, according to their own desires; none of which favors had hindered them from contriving against him, and from bringing his very life into danger, in order to gain his kingdom, after an impious manner, by taking away his life before the course of nature, their father's wishes, or justice required that that kingdom should come to them; and that he wondered what hopes could elevate Antipater to such a pass as to be hardy enough to attempt such things; that he had by his testament in writing declared him his successor in the government; and while he was alive, he was in no respect inferior to him, either in his illustrious dignity, or in power and authority, he having no less than fifty talents for his yearly income, and had received for his journey to Rome no fewer than thirty talents. He also objected to him the case of his brethren whom he had accused; and if they were guilty, he had imitated their example; and if not, he had brought him groundless accusations against his near relations; for that he had been acquainted with all those things by him, and by nobody else, and had done what was done by his approbation, and whom he now absolved from all that was criminal, by becoming the inheritor of the guilt of such their parricide.
