[567] NOW when Antipater had cut off the hopes of the orphans, and had contracted such affinities as would be most for his own advantage, he proceeded briskly, as having a certain expectation of the kingdom; and as he had now assurance added to his wickedness, he became intolerable; for not being able to avoid the hatred of all people, he built his security upon the terror he struck into them. Pheroras also assisted him in his designs, looking upon him as already fixed in the kingdom. There was also a company of women in the court, which excited new disturbances; for Pheroras's wife, together with her mother and sister, as also Antipater's mother, grew very impudent in the palace. She also was so insolent as to affront the king's two daughters, ¹ on which account the king hated her to a great degree; yet although these women were hated by him, they domineered over others: there was only Salome who opposed their good agreement, and informed the king of their meetings, as not being for the advantage of his affairs. And when those women knew what calumnies she had raised against them, and how much Herod was displeased, they left off their public meetings, and friendly entertainments of one another; nay, on the contrary, they pretended to quarrel one with another when the king was within hearing. The like dissimulation did Antipater make use of; and when matters were public, he opposed Pheroras; but still they had private cabals and merry meetings in the night time; nor did the observation of others do any more than confirm their mutual agreement. However, Salome knew every thing they did, and told every thing to Herod.
