[333] HOWEVER, Florus contrived another way to oblige the Jews to begin the war, and sent to Cestius, and accused the Jews falsely of revolting [from the Roman government], and imputed the beginning of the former fight to them, and pretended they had been the authors of that disturbance, wherein they were only the sufferers. Yet were not the governors of Jerusalem silent upon this occasion, but did themselves write to Cestius, as did Bernice also, about the illegal practices of which Florus had been guilty against the city; who, upon reading both accounts, consulted with his captains [what he should do]. Now some of them thought it best for Cestius to go up with his army, either to punish the revolt, if it was real, or to settle the Roman affairs on a surer foundation, if the Jews continued quiet under them; but he thought it best himself to send one of his intimate friends beforehand, to see the state of affairs, and to give him a faithful account of the intentions of the Jews. Accordingly, he sent one of his tribunes, whose name was Neopolitanus, who met with king Agrippa as he was returning from Alexandria, at Jamnia, and told him who it was that sent him, and on what errands he was sent.
