[345] But by this time the Idumeans repented of their coming, and were displeased at what had been done; and when they were assembled together by one of the zealots, who had come privately to them, he declared to them what a number of wicked pranks they had themselves done in conjunction with those that invited them, and gave a particular account of what mischiefs had been done against their metropolis. - He said that they had taken arms, as though the high priests were betraying their metropolis to the Romans, but had found no indication of any such treachery; but that they had succored those that had pretended to believe such a thing, while they did themselves the works of war and tyranny, after an insolent manner. It had been indeed their business to have hindered them from such their proceedings at the first, but seeing they had once been partners with them in shedding the blood of their own countrymen, it was high time to put a stop to such crimes, and not continue to afford any more assistance to such as are subverting the laws of their forefathers; for that if any had taken it ill that the gates had been shut against them, and they had not been permitted to come into the city, yet that those who had excluded them have been punished, and Ananus is dead, and that almost all those people had been destroyed in one night's time. That one may perceive many of themselves now repenting for what they had done, and might see the horrid barbarity of those that had invited them, and that they had no regard to such as had saved them; that they were so impudent as to perpetrate the vilest things, under the eyes of those that had supported them, and that their wicked actions would be laid to the charge of the Idumeans, and would be so laid to their charge till somebody obstructs their proceedings, or separates himself from the same wicked action; that they therefore ought to retire home, since the imputation of treason appears to be a Calumny, and that there was no expectation of the coming of the Romans at this time, and that the government of the city was secured by such walls as cannot easily be thrown down; and, by avoiding any further fellowship with these bad men, to make some excuse for themselves, as to what they had been so far deluded, as to have been partners with them hitherto.
