Numbers 31:22-24

World English Bible

²² However the gold, and the silver, the bronze, the iron, the tin, and the lead, ²³ everything that may withstand the fire, you shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity. All that doesn’t withstand the fire you shall make to go through the water. ²⁴ You shall wash your clothes on the seventh day, and you shall be clean. Afterward you shall come into the camp.”
