The Plague of Leprosy — Leviticus 13:53–59

And if the priest shall look, and, behold, the plague be not spread in the garment, either in the warp, or in the woof, or in anything of skin; then the priest shall command that they wash the thing wherein the plague is, and he shall shut it up seven days more:

and the priest shall look, after that the plague is washed; and, behold, if the plague have not changed its color, 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.

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: 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.

And 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.

This is the law of the plague of leprosy in a garment of woollen or linen, either in the warp, or the woof, or anything of skin, to pronounce it clean, or to pronounce it unclean.
