NET

23 everything that may stand the fire, you are to pass through the fire, and it will be ceremonially clean, but it must still be purified with the water of purification. Anything that cannot withstand the fire you must pass through the water.

Darby

23 everything that passeth through the fire, ye shall make it go through the fire, and it shall be clean; only it shall be purified with the water of separation; and everything that cannot pass through the fire ye shall make go through the water.

KJV

23 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.
