2 Maccabees 12:38 In-Context

36 By now the Jewish men under the command of Esdrias had been fighting for a long time and were exhausted. So Judas prayed that the Lord would show that he was on their side and in command of their troops.
37 Then, while Judas sang a hymn in his native language as a battle cry, the Jews made a surprise attack against Gorgias and his men and put them to flight.
38 After the battle Judas led his men to the town of Adullam. It was the day before the Sabbath, so they purified themselves according to Jewish custom and then observed the holy day.
39 By the following day it was urgent that they gather up the bodies of the men who had been killed in battle and bury them in their family tombs.
40 But on each of the dead, hidden under their clothes, they found small images of the gods worshiped in Jamnia, which the Law forbids Jews to wear. Everyone then knew why these men had been killed.
