The subtle John of Gischala had hitherto professed to support the cause of Ananus, but all the while he maintained a correspondence with the adverse party; and to prevent his double dealing from being suspected, he made such vehement protestations of fidelity to Ananus, and so readily took an oath of obedience and devotion, that the priests and their party were entirely deceived, and admitted him into their most secret councils, and even deputed him to go to the temple, and endeavour to bring their enemies to terms.

The traitor undertook the mission; but no sooner was he within the temple walls, than he threw off the mask, and addressed the robber crew as if he had taken an oath to support them, and not to oppose them. He told them that he had incurred serious dangers in the endeavour to befriend them; that schemes were now being concerted for delivering the city up to the Romans: and that their destruction was inevitable, as Ananus had resolved to get into the temple, either under the pretence of performing worship, or else by main force; and he warned them that if they did not obtain some succour speedily, they would be at the mercy of the enraged populace. The leaders of the Zealots were Eleazer, the old enemy of Ananus, and Zacharias, the son of Phalea. They readily believed that vengeance would be taken on them by the opposing party; and instantly adopting the crafty suggestions of John, they despatched swift messengers to the Idumeans, to demand their assistance.

These fierce and uncivilized people were incorporated with the Jews as one nation; but they retained the love of adventure which belonged to their Arab blood, and the application of the Zealots was received with wild cries of joy. They hastily assembled, and formed themselves into a regular army of twenty thousand men, under the command of James and John the sons of Lofas, Simon the son of Cathlas, and Phineas the son of Clusothas, This numerous and powerful body advanced immediately towards Jerusalem, proclaiming that they were marching to the relief of the capital.

Suddenly they appeared beneath the walls and demanded admittance. The gates were closed, and Jesus, one of the chief priests, was deputed by Ananus to expostulate with them. He proposed to them either to join with the inhabitants in punishing those who caused the present tumult, or to enter without arms and mediate between the contending parties; or else to depart again to their own homes, and leave Jerusalem to finish its own internal war. All these propositions were rudely refused by the Idumeans; and Simon the son of Cathlas, replied, that they came to protect the patriotic party against those who wished to sell them to the Romans, and they were resolved to accomplish this design. His words were received with loud shouts by the Idumeans, and Jesus returned to Ananus, discouraged and apprehensive.

Simon encamped before the gates, and thus the party of Ananus found themselves besieged by two separate forces. The Zealots could not communicate with their new allies, for they were closely shut up in the temple; and the Idumeans could gain no access to them. Their camp was inconvenient, and in an exposed situation; and many of them repented of their hasty march for as night drew on a fearful tempest gathered over the city, and broke with such violence as to strike terror into all who heard it; and every heart trembled in the conviction that it was a dreadful omen of coming destruction and woe. The rain fell in torrents, and was accompanied by terrific thunder and lightning, while the earth shook with the frequent vibrations of an earthquake. The Idumeans were exposed to the violence of the storm, with but little shelter, except their own broad shields, which they locked together over their heads, and thus obtained some protection from the heavy rain; while the Zealots looked forth from their elevated situation in the temple, anxious for the fate of their new allies, and eagerly sought some opportunity of rendering them assistance. Some of the most daring among them proposed to sally forth amid the darkness and tumult of the storm, force their way to the gates, and open them to admit their friends; trusting by the suddenness and fury of their assault, to overpower and scatter the guards who were placed in the outer court. But the more prudent objected strongly to this desperate measure, as they knew that the guards were more numerous than their own party, and also that the city walls and gates were closely watched, to prevent a surprise from the Idumeans. It was likewise the nightly custom of Ananus to pass up and down continually, and see that the sentinels were all at their posts, and he was now expected every moment.

On this one dreadful night, this necessary precaution was omitted. Perhaps Ananus trusted to the strength of the guard, which had been doubled since the arrival of the Idumeans; or perhaps from the violence of the tempest, he felt assured that no attack would be attempted at that time. Whatever were his motives, assuredly they were overruled by an all-directing Providence, and made instrumental in bringing about the destruction and massacre which were permitted that night for the chastisement of a rebellious people. The darkness was profound; the storm raged fearfully; and many of the guard stole away for rest and shelter. This negligence was discovered by the watchful Zealots; and seizing on the sacred instruments of the temple, they proceeded to wrench off the hinges of one of the gates, and thus to open to themselves a way into the streets. The whistling and roaring of the wind, and the loud claps of thunder, drowned the noise of their operations, and a strong party of them reached the walls of the city undiscovered. They immediately applied their saws and crowbars to the gate, near which the Idumeans were encamped, and quickly tore it open.

The Idumeans at first suspected that this was some artifice of Ananus, to draw them on to destruction and they retreated in terror; but soon the Zealots approached, and reassured them, offering to conduct them to victory and revenge; and had they instantly made an attack on the city, nothing could have prevented a fearful and general slaughter. But their guides persuaded them first to hasten to the temple, and rescue the remainder of their party ere the guard should be aroused; for if those who watched the gates were once secured, and the whole band of Zealots released, they were assured that the conquest of the city would soon be accomplished amid the darkness and confusion of night.

Meanwhile the Zealots in the temple were anxiously awaiting the result of their enterprise; and when they found that the Idumeans were entering the sacred enclosure, they boldly came forth and joined them, and then altogether falling on the guard, many of whom were buried in a profound sleep, they commenced a fearful slaughter. The guard at first gathered themselves together, and made head against their assailants; but when they found that the Idumeans were among their foes, they were convinced that the city was betrayed, and the greater part of them threw down their arms in a sudden panic. A few of the youngest and most courageous still maintained the conflict, and supported the attack of the Idumeans, while some of the older men escaped, and fled shrieking down the streets, awaking and alarming the slumbering inhabitants with an announcement of the dreadful calamity. They were answered by the screams and cries of women and children, sounding shrilly through the storm; while the wild shouts of the Idumeans and the Zealots came fearfully from the heights of Mount Moriah, and murky clouds gave forth their awful flashes and pealing thunders. No mercy was shown by the Idumeans to any of the guard who fell into their hands. In vain they appealed to the sanctity of the holy temple for protection; even its most sacred precincts were deluged with blood; and in despair many of the terrified men threw themselves headlong from the lofty rock on which the temple stood, and were dashed to pieces in the deep abyss below.
