Leviticus
Chapters 13:55-59
English Revised Version
55and the priest shall look, after that the plague is washed: and, behold, if the plague have not changed its colour, and the plague be not spread, it is unclean; thou shalt burn it in the fire: it is a fret, whether the bareness be within or without.
56And 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:
57and if it appear still in the garment, either in the warp, or in the woof, or in any thing of skin, it is breaking out: thou shalt burn that wherein the plague is with fire.
58And the garment, either the warp, or the woof, or whatsoever thing of skin it be, which thou shalt wash, if the plague be departed from them, then it shall be washed the second time, and shall be clean.
59This is the law of the plague of leprosy in a garment of woollen or linen, either in the warp, or the woof, or any thing of skin, to pronounce it clean, or to pronounce it unclean.
