2 Maccabees 10:16

16 So Judas Maccabeus and his men, after offering prayers for God's help, rushed out and made a vigorous attack against the Idumean fortresses.

2 Maccabees 10:16 In-Context

14 When Gorgias became governor of Idumea, he kept a force of mercenaries and attacked the Jews at every opportunity.
15 Not only this, but the Idumeans themselves controlled certain strategic fortresses and were constantly harassing the Jews. They welcomed those who fled from Jerusalem and did everything they could to keep the country in a perpetual state of war.
16 So Judas Maccabeus and his men, after offering prayers for God's help, rushed out and made a vigorous attack against the Idumean fortresses.
17 They beat back those who were defending the walls and captured the fortresses, killing everyone they found, a total of about 20,000 people.
18 About 9,000 of the enemy, however, managed to take refuge in two easily defended forts, with everything they needed to withstand a siege.
