Leviticus 13:50-59

⁵⁰And the priest shall look on the sore, and shall shut up that which hath the sore seven days.

⁵¹And he shall see the sore on the seventh day: if the sore have spread in the garment, either in the warp or in the woof, or in a skin, in any work that may be made of skin, the sore is a corroding leprosy: it is unclean.

⁵²And they shall burn the garment, or the warp or the woof, of wool or of linen, or anything of skin, wherein the sore is; for it is a corroding leprosy: it shall be burned with fire.

⁵³But if the priest look, and behold, the sore hath not spread in the garment, or in the warp, or in the woof, or in anything of skin,

⁵⁴then the priest shall command that they wash the thing wherein the sore is, and he shall shut it up seven days a second time.

⁵⁵And the priest shall look on the sore after the washing, and behold, if the sore have not changed its appearance, and the sore have not spread, it is unclean: thou shalt burn it with fire: it is a fretting sore on what is threadbare or where the nap is gone.

⁵⁶But if the priest look, and behold, the sore hath become pale after the washing of it, then he shall rend it from the garment, or from the skin, or from the warp, or from the woof.

⁵⁷And if it appear still in the garment, or in the warp, or in the woof, or in anything of skin, it is a leprosy breaking out: thou shalt burn with fire that wherein the sore is.

⁵⁸But the garment, or the warp, or the woof, or whatever thing of skin which thou hast washed, and the sore departeth from them, it shall be washed a second time, and it is clean.

⁵⁹This is the law of the sore of leprosy in a garment of wool or linen, or in the warp, or in the woof, or in anything of skin, to cleanse it, or to pronounce it unclean.
