19 And encamp ye without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify yourselves on the third day and on the seventh day, ye and your captives. 20 And as to every garment, and all that is made of skin, and all work of goats' [hair], and all things made of wood, ye shall purify yourselves.
21 And Eleazar the priest said unto the men of war that went to the battle, This is the statute of the law which Jehovah hath commanded Moses: 22 howbeit the gold, and the silver, the brass, the iron, the tin, and the lead, 23 everything that may abide the fire, ye shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity: and all that abideth not the fire ye shall make to go through the water. 24 And ye shall wash your clothes on the seventh day, and ye shall be clean; and afterward ye shall come into the camp.

Commentary on Numbers 31:19-24
(Read Numbers 31:19-24)
The Israelites had to purify themselves according to the law, and to abide without the camp seven days, though they had not contracted any moral guilt, the war being just and lawful, and commanded by God. Thus God would preserve in their minds a dread and detestation of shedding blood. The spoil had been used by Midianites, and being now come into the possession of Israelites, it was fit that it should be purified.
