[586] Upon this Herod tortured the maid-servants every on by themselves separately, who all unanimously agreed in the foregoing discoveries, and that accordingly by agreement they went away, Antipater to Rome, and Pheroras to Perea; for that they oftentimes talked to one another thus: That after Herod had slain Alexander and Aristobulus, he would fall upon them, and upon their wives, because, after he Mariamne and her children he would spare nobody; and that for this reason it was best to get as far off the wild beast as they were able: - and that Antipater oftentimes lamented his own case before his mother, and said to her, that he had already gray hairs upon his head, and that his father grew younger again every day, and that perhaps death would overtake him before he should begin to be a king in earnest; and that in case Herod should die, which yet nobody knew when it would be, the enjoyment of the succession could certainly be but for a little time; for that these heads of Hydra, the sons of Alexander and Aristobulus, were growing up: that he was deprived by his father of the hopes of being succeeded by his children, for that his successor after his death was not to be any one of his own sons, but Herod the son of Mariamne: that in this point Herod was plainly distracted, to think that his testament should therein take place; for he would take care that not one of his posterity should remain, because he was of all fathers the greatest hater of his children. Yet does he hate his brother still worse; whence it was that he a while ago gave himself a hundred talents, that he should not have any intercourse with Pheroras. And when Pheroras said, Wherein have we done him any harm? Antipater replied, "I wish he would but deprive us of all we have, and leave us naked and alive only; but it is indeed impossible to escape this wild beast, who is thus given to murder, who will not permit us to love any person openly, although we be together privately; yet may we be so openly too, if we have but the courage and the hands of men."
