Meanwhile the city was distracted by factions, which appeared to be more likely to destroy one another than to maintain a successful defence against an enemy. After the massacre of the Roman troops, Ananus the High Priest, a wise and good man, gained some authority in the city, and endeavoured to counteract the influence of the Zealots. He might have succeeded in averting the war. But Eleazar, the leader of the Zealots, and John of Gischala,[21] the chief of the Galilæans, conspired against him, and by night introduced the Idumæans, in overwhelming force, into the city. By them Ananus and his friends were murdered, and Jerusalem thenceforth was given up to hopeless anarchy. Such authority as there was, rested with the chiefs of the three factions, Eleazar, John, and Simon;[22] but between these there was not only no accord, but the most bitter and persistent animosity. Of the Zealots there were about 2,500, of the Galilæans 6,000, and of the Assassins (as Simon’s followers were called) 10,000 Jews and 5000 Idumæans. Few of these, comparatively speaking, had undergone any military training. But their desperate and fanatical courage, stimulated by their total disregard of all laws, human and Divine, rendered them the most formidable enemies that Rome herself ever encountered. Not only between the three leaders, but their followers also, there subsisted the bitterest hate, which they gratified by continual quarrels and murders; and had it been in their power, they would gladly have exterminated one another. Yet in the field they combined against the common foe with the most perfect unanimity.
