Numbers 31:3-8

King James Version

³ And Moses spake unto the people, saying, Arm some of yourselves unto the war, and let them go against the Midianites, and avenge the Lord of Midian.

⁴ Of every tribe a thousand, throughout all the tribes of Israel, shall ye send to the war.

⁵ So there were delivered out of the thousands of Israel, a thousand of every tribe, twelve thousand armed for war.

⁶ And Moses sent them to the war, a thousand of every tribe, them and Phinehas the son of Eleazar the priest, to the war, with the holy instruments, and the trumpets to blow in his hand.

⁷ And they warred against the Midianites, as the Lord commanded Moses; and they slew all the males.

⁸ And they slew the kings of Midian, beside the rest of them that were slain; namely, Evi, and Rekem, and Zur, and Hur, and Reba, five kings of Midian: Balaam also the son of Beor they slew with the sword.
