[552] BUT an intolerable hatred fell upon Antipater from the nation, though he had now an indisputable title to the succession, because they all knew that he was the person who contrived all the calumnies against his brethren. However, he began to be in a terrible fear, as he saw the posterity of those that had been slain growing up; for Alexander had two sons by Glaphyra, Tigranes and Alexander; and Aristobulus had Herod, and Agrippa, and Aristobulus, his sons, with Herodias and Mariamne, his daughters, and all by Bernice, Salome's daughter. As for Glaphyra, Herod, as soon as he had killed Alexander, sent her back, together with her portion, to Cappadocia. He married Bernice, Aristobulus's daughter, to Antipater's uncle by his mother, and it was Antipater who, in order to reconcile her to him, when she had been at variance with him, contrived this match; he also got into Pheroras's favor, and into the favor of Caesar's friends, by presents, and other ways of obsequiousness, and sent no small sums of money to Rome; Saturninus also, and his friends in Syria, were all well replenished with the presents he made them; yet the more he gave, the more he was hated, as not making these presents out of generosity, but spending his money out of fear. Accordingly, it so fell out that the receivers bore him no more good-will than before, but that those to whom he gave nothing were his more bitter enemies. However, he bestowed his money every day more and more profusely, on observing that, contrary to his expectations, the king was taking care about the orphans, and discovering at the same time his repentance for killing their fathers, by his commiseration of those that sprang from them.
