Leviticus 13:47-59 - Regulations About Contaminated Fabrics
47 And if there is any garment that has the plague of leprosy in it, in a wool garment or a linen garment, 48 or in the warp or in the woof, of linen or of wool, or in a skin or in anything of skin, 49 and if the plague is greenish or reddish in the garment, or in the skin, either in the warp or in the woof, or in anything of skin, it is a plague of leprosy. And it shall be seen by the priest. 50 And the priest shall look on the plague, and shut up that which has the plague seven days. 51 And 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 any skin or in any work that is made of skin, the plague is a fretting leprosy. It is unclean. 52 And he shall burn that garment, whether warp or woof, in wool or in linen, or anything of skin in which the plague is. For it is a fretting leprosy. It shall be burned in the fire.
53 And if the priest shall look, and behold, the plague has not spread in the garment, either in the warp or the woof, or anything of skin, 54 then the priest shall command that they wash the thing in which the plague is. And he shall shut it up seven days more. 55 And the priest shall look on the plague after it is washed, and behold, if the plague has not changed its color and the plague has not spread; it is unclean. You shall burn it in the fire. It is eaten away in its inside or in its outside.
56 And if the priest looks, and behold, the plague is somewhat dark after the washing of it, then he shall tear it out of the garment, or out of the skin, or out of the warp, or out of the woof. 57 And if it appears still in the garment, or in the warp or in the woof, or in anything of skin, it is a spreading plague. You shall burn that which is in it is the plague is with fire. 58 And the garment which you shall wash, either warp or woof, or whatever thing of skin it is, if the plague has departed from them, then it shall be washed a second time, and shall be clean.
59 This is the law of the plague of leprosy in a garment of woolen or linen, either in the warp or woof or anything of skins, to pronounce it clean or to pronounce it unclean.
