[431] HOWEVER, fortune was avenged on Herod in his external great successes, by raising him up domestical troubles; and he began to have wild disorders in his family, on account of his wife, of whom he was so very fond. For when he came to the government, he sent away her whom he had before married when he was a private person, and who was born at Jerusalem, whose name was Doris, and married Mariamne, the daughter of Alexander, the son of Aristobulus; on whose account disturbances arose in his family, and that in part very soon, but chiefly after his return from Rome. For, first of all, he expelled Antipater the son of Doris, for the sake of his sons by Mariamne, out of the city, and permitted him to come thither at no other times than at the festivals. After this he slew his wife's grandfather, Hyrcanus, when he was returned out of Parthin to him, under this pretense, that he suspected him of plotting against him. Now this Hyrcanus had been carried captive to Barzapharnes, when he overran Syria; but those of his own country beyond Euphrates were desirous he would stay with them, and this out of the commiseration they had for his condition; and had he complied with their desires, when they exhorted him not to go over the river to lierod, he had not perished: but the marriage of his granddaughter [to Herod] was his temptation; for as he relied upon him, and was over-fond of his own country, he came back to it. Herod's provocation was this, - not that Hyrcanus made any attempt to gain the kingdom, but that it was fitter for him to be their king than for Herod.
