Numbers 31:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ Eleazar the priest said to the troops who had gone to battle: ‘This is the statute of the law that the Lord has commanded Moses: ²² gold, silver, bronze, iron, tin, and lead— ²³ everything that can withstand fire, shall be passed through fire, and it shall be clean. Nevertheless it shall also be purified with the water for purification; and whatever cannot withstand fire, shall be passed through the water.
