Numbers 31:10-21
English Standard Version
Chapter 31
10All their cities in the places where they lived, and all their encampments, they burned with fire, 11and took all the spoil and all the plunder, both of man and of beast. 12Then they brought the captives and the plunder and the spoil to Moses, and to Eleazar the priest, and to the congregation of the people of Israel, at the camp on the plains of Moab by the Jordan at Jericho.
13Moses and Eleazar the priest and all the chiefs of the congregation went to meet them outside the camp.
14And Moses was angry with the officers of the army, the commanders of thousands and the commanders of hundreds, who had come from service in the war.
15Moses said to them, "Have you let all the women live?
16Behold, these, on Balaam 's advice, caused the people of Israel to act treacherously against the Lord in the incident of Peor, and so the plague came among the congregation of the Lord.
17Now therefore, kill every male among the little ones, and kill every woman who has known man by lying with him.
18But all the young girls who have not known man by lying with him keep alive for yourselves.
19Encamp outside the camp seven days. Whoever of you has killed any person and whoever has touched any slain, purify yourselves and your captives on the third day and on the seventh day.
20You shall purify every garment, every article of skin, all work of goats ' hair, and every article of wood."
