Numbers 31:5-7

Darby Translation

⁵ And there were levied out of the thousands of Israel, a thousand by tribe, twelve thousand armed for war.

⁶ And Moses sent them to the war, a thousand by the tribe, them and Phinehas the son of Eleazar the priest, to the war, and the holy instruments, even the alarm-trumpets in his hand.

⁷ And they warred against Midian, as Jehovah had commanded Moses, and slew all the males.
