2 Maccabees 10:13-23

13 As a result the King's Friends went to Eupator and accused Macron of treachery, because he had abandoned the island of Cyprus, which King Philometor of Egypt had placed under his command, and had gone over to Antiochus Epiphanes. In fact, everyone called Macron a traitor. No longer able to maintain the respect that his office demanded, he committed suicide by taking poison.
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.
19 Judas had to go on to some other places in the country, where he was more urgently needed, but he left behind Simon and Joseph, together with Zacchaeus and his men. This force was large enough to continue the siege,
20 but some of Simon's men were greedy, and when they were offered 140 pounds of silver, they let some of the enemy escape from the forts.
21 When Judas heard what had happened, he called together the leaders of his troops and accused those men of selling their brothers by setting their enemies free to fight against them.
22 Then he executed the traitors and immediately captured the two forts.
23 Judas was always successful in battle, and in his assault on those two forts he killed more than 20,000 men.
