II Maccabees 13:15

15 And having given the watchword to them that were about him, Victory is of God; with the most valiant and choice young men he went in into the king's tent by night, and slew in the camp about four thousand men, and the chiefest of the elephants, with all that were upon him.

II Maccabees 13:15 In-Context

13 And Judas, being apart with the elders, determined, before the king's host should enter into Judea, and get the city, to go forth and try the matter in fight by the help of the Lord.
14 So when he had committed all to the Creator of the world, and exhorted his soldiers to fight manfully, even unto death, for the laws, the temple, the city, the country, and the commonwealth, he camped by Modin:
15 And having given the watchword to them that were about him, Victory is of God; with the most valiant and choice young men he went in into the king's tent by night, and slew in the camp about four thousand men, and the chiefest of the elephants, with all that were upon him.
16 And at last they filled the camp with fear and tumult, and departed with good success.
17 This was done in the break of the day, because the protection of the Lord did help him.
