[398] And now a fourth misfortune arose, in order to bring our nation to destruction. There was a fortress of very great strength not far from Jerusalem, which had been built by our ancient kings, both as a repository for their effects in the hazards of war, and for the preservation of their bodies at the same time. It was called Masada. Those that were called Sicarii had taken possession of it formerly, but at this time they overran the neighboring countries, aiming only to procure to themselves necessaries; for the fear they were then in prevented their further ravages. But when once they were informed that the Roman army lay still, and that the Jews were divided between sedition and tyranny, they boldly undertook greater matters; and at the feast of unleavened bread, which the Jews celebrate in memory of their deliverance from the Egyptian bondage, when they were sent back into the country of their forefathers, they came down by night, without being discovered by those that could have prevented them, and overran a certain small city called Engaddi:--in which expedition they prevented those citizens that could have stopped them, before they could arm themselves, and fight them. They also dispersed them, and cast them out of the city. As for such as could not run away, being women and children, they slew of them above seven hundred. Afterward, when they had carried every thing out of their houses, and had seized upon all the fruits that were in a flourishing condition, they brought them into Masada. And indeed these men laid all the villages that were about the fortress waste, and made the whole country desolate; while there came to them every day, from all parts, not a few men as corrupt as themselves. At that time all the other regions of Judea that had hitherto been at rest were in motion, by means of the robbers. Now as it is in a human body, if the principal part be inflamed, all the members are subject to the same distemper; so, by means of the sedition and disorder that was in the metropolis,. had the wicked men that were in the country opportunity to ravage the same. Accordingly, when every one of them had plundered their own villages, they then retired into the desert; yet were these men that now got together, and joined in the conspiracy by parties, too small for an army, and too many for a gang of thieves: and thus did they fall upon the holy places ¹ and the cities; yet did it now so happen that they were sometimes very ill treated by those upon whom they fell with such violence, and were taken by them as men are taken in war: but still they prevented any further punishment as do robbers, who, as soon as their ravages [are discovered], run their way. Nor was there now any part of Judea that was not in a miserable condition, as well as its most eminent city also.
