Numbers 31:5 WBT

³  And Moses spoke to the people, saying, Arm some of yourselves for the war, and let them go against the Midianites, and avenge the LORD on 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.
