Numbers 31:22-24

New American Standard Bible

²² only the gold and the silver, the bronze, the iron, the tin, and the lead, ²³ everything that can ^[a]withstand the fire, you shall pass through the fire, and it will be clean, only it shall be purified with ^(A)water for impurity. But whatever cannot ^[b]withstand the fire you shall pass through the water. ²⁴ And you shall wash your clothes on the seventh day and you will be clean; and afterward you may enter the camp.”
