[22] However, Simon and Jonathan returned to the lakes of the river, and abode there. But Bacchides, when he had secured all Judea with his garrisons, returned to the king; and then it was that the affairs of Judea were quiet for two years. But when the deserters and the wicked saw that Jonathan and those that were with him lived in the country very quietly, by reason of the peace, they sent to king Demetrius, and excited him to send Bacchides to seize upon Jonathan, which they said was to be done without any trouble, and in one night's time; and that if they fell upon them before they were aware, they might slay them all. So the king sent Bacchides, who, when he was come into Judea, wrote to all his friends, both Jews and auxiliaries, that they should seize upon Jonathan, and bring him to him; and when, upon all their endeavors, they were not able to seize upon Jonathan, for he was sensible of the snares they laid for him, and very carefully guarded against them, Bacchides was angry at these deserters, as having imposed upon him, and upon the king, and slew fifty of their leaders: whereupon Jonathan, with his brother, and those that were with him, retired to Bethagla, a village that lay in the wilderness, out of his fear of Bacchides. He also built towers in it, and encompassed it with walls, and took care that it should be safely guarded. Upon the hearing of which Bacchides led his own army along with him, and besides took his Jewish auxiliaries, and came against Jonathan, and made an assault upon his fortifications, and besieged him many days; but Jonathan did not abate of his courage at the zeal Bacchides used in the siege, but courageously opposed him. And while he left his brother Simon in the city to fight with Bacchides, he went privately out himself into the country, and got a great body of men together of his own party, and fell upon Bacchides's camp in the night time, and destroyed a great many of them. His brother Simon knew also of this his falling upon them, because he perceived that the enemies were slain by him; so he sallied out upon them, and burnt the engines which the Macedonians used, and made a great slaughter of them. And when Bacchides saw himself encompassed with enemies, and some of them before and some behind him, he fell into despair and trouble of mind, as confounded at the unexpected ill success of this siege. However, he vented his displeasure at these misfortunes upon those deserters who sent for him from the king, as having deluded him. So he had a mind to finish this siege after a decent manner, if it were possible for him so to do, and then to return home.
