2 Maccabees 12:37

37 And with that he began in his own language and sang psalms with a loud voice and, rushing unawares upon Gorgias' men, he put them to flight.

2 Maccabees 12:37 In-Context

35 At that time Dositheus, one of Bacenor's company who was on horseback and a strong man, silently crept up upon Gorgias and, taking hold of his coat, drew him by force; and when he would have taken that accursed man alive, a horseman of Thracia, coming upon him, smote off his shoulder, so that Gorgias fled unto Marisa.

36 Now when those who were with Gorgias had fought long and were weary, Judas called upon the Lord, that He would show Himself to be their helper and leader of the battle.

37 And with that he began in his own language and sang psalms with a loud voice and, rushing unawares upon Gorgias' men, he put them to flight.

38 So Judas gathered his host and came into the city of Adullam. And when the seventh day came, they purified themselves, as the custom was, and kept the Sabbath in the same place.

39 And upon the day following, as the practice had been, Judas and his company came to take up the bodies of those who were slain, and to bury them with their kinsmen in their fathers' graves.
