15 Besides this, the Idumeans, who had control of important strongholds, were harassing the Jews; they received those who were banished from Jerusalem, and endeavored to keep up the war.

2 Maccabees 10:15 In-Context

13 As a result he was accused before Eupator by the king's Friends. He heard himself called a traitor at every turn, because he had abandoned Cyprus, which Philometor had entrusted to him, and had gone over to Antiochus Epiphanes. Unable to command the respect due his office, he took poison and ended his life.
14 When Gorgias became governor of the region, he maintained a force of mercenaries, and at every turn kept attacking the Jews.
15 Besides this, the Idumeans, who had control of important strongholds, were harassing the Jews; they received those who were banished from Jerusalem, and endeavored to keep up the war.
16 But Maccabeus and his forces, after making solemn supplication and imploring God to fight on their side, rushed to the strongholds of the Idumeans.
17 Attacking them vigorously, they gained possession of the places, and beat off all who fought upon the wall, and slaughtered those whom they encountered, killing no fewer than twenty thousand.
