[5] For Eleazar, the son of Simon, who made the first separation of the zealots from the people, and made them retire into the temple, appeared very angry at John's insolent attempts, which he made everyday upon the people; for this man never left off murdering; but the truth was, that he could not bear to submit to a tyrant who set up after him. So he being desirous of gaining the entire power and dominion to himself, revolted from John, and took to his assistance Judas the son of Chelcias, and Simon the son of Ezron, who were among the men of greatest power. There was also with him Hezekiah, the son of Chobar, a person of eminence. Each of these were followed by a great many of the zealots; these seized upon the inner court of the temple ¹ and laid their arms upon the holy gates, and over the holy fronts of that court. And because they had plenty of provisions, they were of good courage, for there was a great abundance of what was consecrated to sacred uses, and they scrupled not the making use of them; yet were they afraid, on account of their small number; and when they had laid up their arms there, they did not stir from the place they were in. Now as to John, what advantage he had above Eleazar in the multitude of his followers, the like disadvantage he had in the situation he was in, since he had his enemies over his head; and as he could not make any assault upon them without some terror, so was his anger too great to let them be at rest; nay, although he suffered more mischief from Eleazar and his party than he could inflict upon them, yet would he not leave off assaulting them, insomuch that there were continual sallies made one against another, as well as darts thrown at one another, and the temple was defiled every where with murders.
