[532] After this fight was over, Vespasian sat upon his tribunal at Taricheae, in order to distinguish the foreigners from the old inhabitants; for those foreigners appear to have begun the war. So he deliberated with the other commanders, whether he ought to save those old inhabitants or not. And when those commanders alleged that the dismission of them would be to his own disadvantage, because, when they were once set at liberty, they would not be at rest, since they would be people destitute of proper habitations, and would he able to compel such as they fled to fight against us, Vespasian acknowledged that they did not deserve to be saved, and that if they had leave given them to fly away, they would make use of it against those that gave them that leave. But still he considered with himself after what manner they should be slain ¹ for if he had them slain there, he suspected the people of the country would thereby become his enemies; for that to be sure they would never bear it, that so many that had been supplicants to him should be killed; and to offer violence to them, after he had given them assurances of their lives, he could not himself bear to do it. However, his friends were too hard for him, and pretended that nothing against Jews could be any impiety, and that he ought to prefer what was profitable before what was fit to be done, where both could not be made consistent. So he gave them an ambiguous liberty to do as they advised, and permitted the prisoners to go along no other road than that which led to Tiberias only. So they readily believed what they desired to be true, and went along securely, with their effects, the way which was allowed them, while the Romans seized upon all the road that led to Tiberias, that none of them might go out of it, and shut them up in the city. Then came Vespasian, and ordered them all to stand in the stadium, and commanded them to kill the old men, together with the others that were useless, which were in number a thousand and two hundred. Out of the young men he chose six thousand of the strongest, and sent them to Nero, to dig through the Isthmus, and sold the remainder for slaves, being thirty thousand and four hundred, besides such as he made a present of to Agrippa; for as to those that belonged to his kingdom, he gave him leave to do what he pleased with them; however, the king sold these also for slaves; but for the rest of the multitude, who were Trachonites, and Gaulanites, and of Hippos, and some of Gadara, the greatest part of them were seditious persons and fugitives, who were of such shameful characters, that they preferred war before peace. These prisoners were taken on the eighth day of the month Gorpiaeus [Elul].
