Leviticus 13:50-59

⁵⁰And the priest shall look upon the plague, and shut up that which hath the plague seven days:

⁵¹And he shall look on the plague on the seventh day: if the plague is spread in the garment, either in the warp, or in the woof, or in a skin, or in any work that is made of skin: the plague is a fretting leprosy; it is unclean.

⁵²He shall therefore burn that garment, whether warp or woof, in woolen or in linen, or any thing of skin, in which the plague is: for it is a fretting leprosy; it shall be burnt in the fire.

⁵³And if the priest shall look, and behold, the plague is not spread in the garment, either in the warp or in the woof, or in any thing of skin;

⁵⁴Then the priest shall command that they wash the thing in which the plague is , and he shall shut it up seven days more:

⁵⁵And the priest shall look on the plague after it is washed: and behold, if the plague hath not changed its color, and the plague hath not spread; it is unclean; thou shalt burn it in the fire; it is fret inward, whether it is bare within or without.

⁵⁶And if the priest shall look, and behold, the plague is somewhat dark after the washing of it; 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 shall appear still in the garment, either in the warp, or in the woof, or in any thing of skin; it is a spreading plague : thou shalt burn that in which the plague is , with fire.

⁵⁸And the garment, either warp, or woof, or whatever thing of skin it is , which thou shalt wash, if the plague hath 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 woolen or linen, either in the warp or woof, or any thing of skins, to pronounce it clean, or to pronounce it unclean.
