Numbers 31:19-24

Revised Standard Version

¹⁹ Encamp 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. ²⁰ You shall purify every garment, every article of skin, all work of goats’ hair, and every article of wood.”

²¹ And Elea′zar the priest said to the men of war who had gone to battle: “This is the statute of the law which the Lord has commanded Moses: ²² only the gold, the silver, the bronze, the iron, the tin, and the lead, ²³ everything 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 of impurity; and whatever cannot stand the fire, you shall pass through the water. ²⁴ You must wash your clothes on the seventh day, and you shall be clean; and afterward you shall come into the camp.”
