Flavius Josephus, The Wars of the Jews
William Whiston, A.M., Ed.

[498] NOW as to Alexander, since he perceived it impossible to persuade his father [that he was innocent], he resolved to meet his calamities, how severe soever they were; so he composed four books against his enemies, and confessed that he had been in a plot; but declared withal that the greatest part [of the courtiers] were in a plot with him, and chiefly Pheroras and Salome; nay, that Salome once came and forced him to lie with her in the night time, whether he would or no. These books were put into Herod's hands, and made a great clamor against the men in power. And now it was that Archelaus came hastily into Judea, as being affrighted for his son-in-law and his daughter; and he came as a proper assistant, and in a very prudent manner, and by a stratagem he obliged the king not to execute what he had threatened; for when he was come to him, he cried out, "Where in the world is this wretched son-in-law of mine? Where shall I see the head of him which contrived to murder his father, which I will tear to pieces with my own hands? I will do the same also to my daughter, who hath such a fine husband; for although she be not a partner in the plot, yet, by being the wife of such a creature, she is polluted. And I cannot but admire at thy patience, against whom this plot is laid, if Alexander be still alive; for as I came with what haste I could from Cappadocia, I expected to find him put to death for his crimes long ago; but still, in order to make an examination with thee about my daughter, whom, out of regard to thee and by dignity, I had espoused to him in marriage; but now we must take counsel about them both; and if thy paternal affection be so great, that thou canst not punish thy son, who hath plotted against thee, let us change our right hands, and let us succeed one to the other in expressing our rage upon this occasion."
