[362] At this time it was that the garrison in the citadel of Jerusalem, with the Jewish runagates, did a great deal of harm to the Jews; for the soldiers that were in that garrison rushed out upon the sudden, and destroyed such as were going up to the temple in order to offer their sacrifices, for this citadel adjoined to and overlooked the temple. When these misfortunes had often happened to them, Judas resolved to destroy that garrison; whereupon he got all the people together, and vigorously besieged those that were in the citadel. This was in the hundred and fiftieth year of the dominion of the Seleucidse. So he made engines of war, and erected bulwarks, and very zealously pressed on to take the citadel. But there were not a few of the runagates who were in the place that went out by night into the country, and got together some other wicked men like themselves, and went to Antiochus the king, and desired of him that he would not suffer them to be neglected, under the great hardships that lay upon them from those of their own nation; and this because their sufferings were occasioned on his father's account, while they left the religious worship of their fathers, and preferred that which he had commanded them to follow: that there was danger lest the citadel, and those appointed to garrison it by the king, should be taken by Judas, and those that were with him, unless he would send them succors. When Antiochus, who was but a child, heard this, he was angry, and sent for his captains and his friends, and gave order that they should get an army of mercenaries together, with such men also of his own kingdom as were of an age fit for war. Accordingly, an army was collected of about a hundred thousand footmen, and twenty thousand horsemen, and thirty-two elephants.
