[417] And as they said these things, they produced those priests that were skillful in the customs of their country, who made the report that all their forefathers had received the sacrifices from foreign nations. But still not one of the innovators would hearken to what was said; nay, those that ministered about the temple would not attend their Divine service, but were preparing matters for beginning the war. So the men of power perceiving that the sedition was too hard for them to subdue, and that the danger which would arise from the Romans would come upon them first of all, endeavored to save themselves, and sent ambassadors, some to Florus, the chief of which was Simon the son of Ananias; and others to Agrippa, among whom the most eminent were Saul, and Antipas, and Costobarus, who were of the king's kindred; and they desired of them both that they would come with an army to the city, and cut off the seditious before it should be too hard to be subdued. Now this terrible message was good news to Florus; and because his design was to have a war kindled, he gave the ambassadors no answer at all. But Agrippa was equally solicitous for those that were revolting, and for those against whom the war was to be made, and was desirous to preserve the Jews for the Romans, and the temple and metropolis for the Jews; he was also sensible that it was not for his own advantage that the disturbances should proceed; so he sent three thousand horsemen to the assistance of the people out of Auranitis, and Batanea, and Trachonitis, and these under Darius, the master of his horse, and Philip the son of Jacimus, the general of his army.
