Numbers 31:7-11

So they made war against Midian, just as the Lord had commanded Moses, and they killed every male.

They killed the kings of Midian along with the rest of those killed: Evi, Rekem, Zur, Hur, and Reba, the five kings of Midian. They also killed Balaam the son of Beor with the sword.

And the sons of Israel took captive the women of Midian and their little ones; and they plundered all their cattle, all their flocks, and all their property.

Then they burned all their cities where they lived and all their encampments.

And they took all the plunder and all the spoils, both of people and of livestock.
