2 Maccabees 10:15-17

New Revised Standard Version Catholic Edition

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.
