[248] NOW the warlike men that were in the city, and the multitude of the seditious that were with Simon, were ten thousand, besides the Idumeans. Those ten thousand had fifty commanders, over whom this Simon was supreme. The Idumeans that paid him homage were five thousand, and had eight commanders, among whom those of greatest fame were Jacob the son of Sosas, and Simon the son of Cathlas. Jotre, who had seized upon the temple, had six thousand armed men under twenty commanders; the zealots also that had come over to him, and left off their opposition, were two thousand four hundred, and had the same commander that they had formerly, Eleazar, together with Simon the son of Arinus. Now, while these factions fought one against another, the people were their prey on both sides, as we have said already; and that part of the people who would not join with them in their wicked practices were plundered by both factions. Simon held the upper city, and the great wall as far as Cedron, and as much of the old wall as bent from Siloam to the east, and which went down to the palace of Monobazus, who was king of the Adiabeni, beyond Euphrates; he also held that fountain, and the Acra, which was no other than the lower city; he also held all that reached to the palace of queen Helena, the mother of Monobazus. But John held the temple, and the parts thereto adjoining, for a great way, as also Ophla, and the valley called "the Valley of Cedron;" and when the parts that were interposed between their possessions were burnt by them, they left a space wherein they might fight with each other; for this internal sedition did not cease even when the Romans were encamped near their very wall. But although they had grown wiser at the first onset the Romans made upon them, this lasted but a while; for they returned to their former madness, and separated one from another, and fought it out, and did everything that the besiegers could desire them to do; for they never suffered any thing that was worse from the Romans than they made each other suffer; nor was there any misery endured by the city after these men's actions that could be esteemed new. But it was most of all unhappy before it was overthrown, while those that took it did it a greater kindness for I venture to affirm that the sedition destroyed the city, and the Romans destroyed the sedition, which it was a much harder thing to do than to destroy the walls; so that we may justly ascribe our misfortunes to our own people, and the just vengeance taken on them to the Romans; as to which matter let every one determine by the actions on both sides.
