Numbers 31:21-23

International Standard Version

²¹ Eleazar the priest told the soldiers who had gone to battle, “This is the ordinance of the law that the Lord commanded Moses ²² concerning anything containing gold, silver, brass, iron, tin, lead, ²³ or anything else that can survive a refiner’s fire: You are to pass it through fire, after which it will be clean. Then it is to be purified with the water of impurity. Everything that cannot survive a refiner’s fire is to be washed in water.
