Numbers 31:7-17

7They attacked Midian as the Lord had commanded Moses, and they killed all the men.

8All five of the Midianite kings—Evi, Rekem, Zur, Hur, and Reba—died in the battle. They also killed Balaam son of Beor with the sword.

9Then the Israelite army captured the Midianite women and children and seized their cattle and flocks and all their wealth as plunder.

10They burned all the towns and villages where the Midianites had lived.

11After they had gathered the plunder and captives, both people and animals,

12they brought them all to Moses and Eleazar the priest, and to the whole community of Israel, which was camped on the plains of Moab beside the Jordan River, across from Jericho.

13Moses, Eleazar the priest, and all the leaders of the community went to meet them outside the camp.

14But Moses was furious with all the generals and captains who had returned from the battle.

15“Why have you let all the women live?” he demanded.

16“These are the very ones who followed Balaam’s advice and caused the people of Israel to rebel against the Lord at Mount Peor. They are the ones who caused the plague to strike the Lord’s people.

17So kill all the boys and all the women who have had intercourse with a man.
