[390] About this time it was that Justus, the son of Pistus, without my knowledge, ran away to the king; the occasion of which I will here relate. Upon the beginning of the war between the Jews and Romans, the people of Tiberias resolved to submit to the king, and not to revolt from the Romans; while Justus tried to persuade them to betake themselves to their arms, as being himself desirous of innovations, and having hopes of obtaining the government of Galilee, as well as of his own country [Tiberias] also. Yet did he not obtain what he hoped for, because the Galileans bore ill-will to those of Tiberias, and this on account of their anger at what miseries they had suffered from them before the war; thence it was that they would not endure that Justus should be their governor. I myself also, who had been intrusted by the community of Jerusalem with the government of Galilee, did frequently come to that degree of rage at Justus, that I had almost resolved to kill him, as not able to bear his mischievous disposition. He was therefore much afraid of me, lest at length my passion should come to extremity; so he went to the king, as supposing that he would dwell better and more safely with him.
