Leviticus 13:56-57

American Standard Version

⁵⁶ And if the priest look, and, behold, the plague be dim after the washing thereof, then he shall rend it out of the garment, or out of the skin, or out of the warp, or out of the woof: ⁵⁷ and if it appear still in the garment, either in the warp, or in the woof, or in anything of skin, it is breaking out: thou shalt burn that wherein the plague is with fire.
