Numbers 31:22-24

New King James Version

²² Only the gold, the silver, the bronze, the iron, the tin, and the lead, ²³ everything that can endure fire, you shall put through the fire, and it shall be clean; and it shall be purified ^(A)with the water of purification. But all that cannot endure fire you shall put through water. ^24 (B)And you shall wash your clothes on the seventh day and be clean, and afterward you may come into the camp.”
