The Israelites captured the Midianite women and children and took all the Midianite herds, flocks and goods as plunder. They burned all the towns where the Midianites had settled, as well as all their camps. They took all the plunder and spoils, including the people and animals, and brought the captives, spoils and plunder to Moses and Eleazar the priest and the Israelite assembly at their camp on the plains of Moab, by the Jordan across from Jericho.Bible: Numbers 31,9-18 New International Version (NIV)
Moses, Eleazar the priest and all the leaders of the community went to meet them outside the camp. Moses was angry with the officers of the army—the commanders of thousands and commanders of hundreds—who returned from the battle.
“Have you allowed all the women to live?” he asked them. “They were the ones who followed Balaam’s advice and enticed the Israelites to be unfaithful to the Lord in the Peor incident, so that a plague struck the Lord’s people. Now kill all the boys. And kill every woman who has slept with a man, but save for yourselves every girl who has never slept with a man.
