Numbers 31:21–23

Then Eleazar the priest said to the men in the army who had gone to battle: “This is the statute of the law that the Lord has commanded Moses: only the gold, the silver, the bronze, the iron, the tin, and the lead, everything that can stand the fire, you shall pass through the fire, and it shall be clean. Nevertheless, it shall also be purified with the water for impurity. And whatever cannot stand the fire, you shall pass through the water.

Then Eleazar the priest said to the soldiers who had gone into battle, “This is what is required by the law that the Lord gave Moses: Gold, silver, bronze, iron, tin, lead and anything else that can withstand fire must be put through the fire, and then it will be clean. But it must also be purified with the water of cleansing. And whatever cannot withstand fire must be put through that water.

Then the priest Eleazar said to the soldiers who had gone to battle, “This is the legal statute the Lord commanded Moses: The gold, silver, bronze, iron, tin, and lead—everything that can withstand fire—you are to pass through fire, and it will be clean. It must still be purified with the purification water. Anything that cannot withstand fire, pass through the water.

Then Eleazar the priest said to the men who were in the battle, “The Lord has given Moses this legal requirement: Anything made of gold, silver, bronze, iron, tin, or lead—that is, all metals that do not burn—must be passed through fire in order to be made ceremonially pure. These metal objects must then be further purified with the water of purification. But everything that burns must be purified by the water alone.

Then Eleazar the priest said to the men of the battle who came from the war, “This is the decree of the law that Yahweh commanded Moses. Only the gold and the silver, the bronze, the iron, the tin, and the lead—everything that will go through the fire—you will pass through the fire, and it will be clean, and only in waters of impurity will it be purified. Whatever does not go into the fire you will pass through the waters.

And Eleazar the priest said unto the men of war which went to the battle, This is the ordinance of the law which the Lord commanded Moses; Only the gold, and the silver, the brass, the iron, the tin, and the lead, Every thing that may abide the fire, ye shall make it go through the fire, and it shall be clean: nevertheless it shall be purified with the water of separation: and all that abideth not the fire ye shall make go through the water.
