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

[379] Now as Alexander fled to the mountains, six thousand of the Jews hereupon came together [from Demetrius] to him out of pity at the change of his fortune; upon which Demetrius was afraid, and retired out of the country; after which the Jews fought against Alexander, and being beaten, were slain in great numbers in the several battles which they had; and when he had shut up the most powerful of them in the city Bethome, he besieged them therein; and when he had taken the city, and gotten the men into his power, he brought them to Jerusalem, and did one of the most barbarous actions in the world to them; for as he was feasting with his concubines, in the sight of all the city, he ordered about eight hundred of them to be crucified; and while they were living, he ordered the throats of their children and wives to be cut before their eyes. This was indeed by way of revenge for the injuries they had done him; which punishment yet was of an inhuman nature, though we suppose that he had been never so much distressed, as indeed he had been, by his wars with them, for he had by their means come to the last degree of hazard, both of his life and of his kingdom, while they were not satisfied by themselves only to fight against him, but introduced foreigners also for the same purpose; nay, at length they reduced him to that degree of necessity, that he was forced to deliver back to the king of Arabia the land of Moab and Gilead, which he had subdued, and the places that were in them, that they might not join with them in the war against him, as they had done ten thousand other things that tended to affront and reproach him. However, this barbarity seems to have been without any necessity, on which account he bare the name of a Thracian among the Jews ¹ whereupon the soldiers that had fought against him, being about eight thousand in number, ran away by night, and continued fugitives all the time that Alexander lived; who being now freed from any further disturbance from them, reigned the rest of his time in the utmost tranquillity.
