Wars of the Jews Josephus Book 6
CHAPTER 3.
CONCERNING A STRATAGEM THAT WAS DEVISED BY THE JEWS, BY WHICH THEY BURNT MANY OF THE ROMANS; WITH ANOTHER DESCRIPTION OF THE TERRIBLE FAMINE THAT WAS IN THE CITY.
1. BUT now the seditious that were in the temple did every day openly endeavor to beat off the soldiers that were upon the banks, and on the twenty-seventh day of the forenamed month [Panemus or Tamuz] contrived such a stratagem as this: They filled that part of the western cloister (14) which was between the beams, and the roof under them, with dry materials, as also with bitumen and pitch, and then retired from that place, as though they were tired with the pains they had taken; at which procedure of theirs, many of the most inconsiderate among the Romans, who were carried away with violent passions, followed hard after them as they were retiring, and applied ladders to the cloister, and got up to it suddenly; but the prudent part of them, when they understood this unaccountable retreat of the Jews, stood still where they were before. However, the cloister was full of those that were gone up the ladders;
at which time the Jews set it all on fire; and as the flame burst out every where on the sudden, the Romans that were out of the danger were seized with a very great consternation, as were those that were in the midst of the danger in the utmost distress.-----
2--------But the next day the Romans burnt down the northern cloister entirely, as far as the east cloister, whose common angle joined to the valley that was called Cedron, and was built over it; on which account the depth was frightful. And this was the state of the temple at that time.
5. This sad instance was quickly told to the Romans, some of whom could not believe it, and others pitied the distress which the Jews were under; but there were many of them who were hereby induced to a more bitter hatred than ordinary against our nation. But for Caesar, he excused himself before God as to this matter,
and said that he had proposed peace and liberty to the Jews, as well as an oblivion of all their former insolent practices; but that they, instead of concord, had chosen sedition; instead of peace, war; and before satiety and abundance, a famine.
That they had begun with their own hands to burn down that temple which we have preserved hitherto; and that therefore they deserved to eat such food as this was. That, however, this horrid action of eating an own child ought to be covered with the overthrow of their very country itself, and men ought not to leave such a city upon the habitable earth to be seen by the sun, wherein mothers are thus fed, although such food be fitter for the fathers than for the mothers to eat of, since it is they that continue still in a state of war against us, after they have undergone such miseries as these. And at the same time that he said this, he reflected on the desperate condition these men must be in; nor could he expect that such men could be recovered to sobriety of mind, after they had endured those very sufferings, for the avoiding whereof it only was probable they might have repented.
