Numbers 31:17-28
English Standard Version
Chapter 31
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."
21Then Eleazar the priest said to the men in the army who had gone to battle: "This is the statute of the law that the Lord has commanded Moses:
22only the gold, the silver, the bronze, the iron, the tin, and the lead,
23everything that can stand the fire, you shall pass through the fire, and it shall be clean. Nevertheless, it shall also be purified with the water for impurity. And whatever cannot stand the fire, you shall pass through the water.
24You must wash your clothes on the seventh day, and you shall be clean. And afterward you may come into the camp."
25The Lord said to Moses,
26"Take the count of the plunder that was taken, both of man and of beast, you and Eleazar the priest and the heads of the fathers ' houses of the congregation,
27and divide the plunder into two parts between the warriors who went out to battle and all the congregation.
28And levy for the Lord a tribute from the men of war who went out to battle, one out of five hundred, of the people and of the oxen and of the donkeys and of the flocks.
