Numbers 31:7-9

Young's Literal Translation

⁷ And they war against Midian, as Jehovah hath commanded Moses, and slay every male;

⁸ and the kings of Midian they have slain, besides their pierced ones, Evi, and Rekem, and Zur, and Hur, and Reba, five kings of Midian; and Balaam son of Beor, they have slain with the sword.

⁹ And the sons of Israel take captive the women of Midian, and their infants; and all their cattle, and all their substance, and all their wealth they have plundered;
