Leviticus 13:50-59

⁵⁰The priest shall examine the plague, and isolate the plague seven days.

⁵¹He shall examine the plague on the seventh day. If the plague has spread in the garment, either in the warp, or in the woof, or in the skin, whatever use the skin is used for, the plague is a destructive mildew. It is unclean.

⁵²He shall burn the garment, whether the warp or the woof, in wool or in linen, or anything of leather, in which the plague is, for it is a destructive mildew. It shall be burnt in the fire.

⁵³“If the priest examines it, and behold, the plague hasn’t spread in the garment, either in the warp, or in the woof, or in anything of skin;

⁵⁴then the priest shall command that they wash the thing that the plague is in, and he shall isolate it seven more days.

⁵⁵Then the priest shall examine it, after the plague is washed; and behold, if the plague hasn’t changed its colour, and the plague hasn’t spread, it is unclean; you shall burn it in the fire. It is a mildewed spot, whether the bareness is inside or outside.

⁵⁶If the priest looks, and behold, the plague has faded after it is washed, then he shall tear it out of the garment, or out of the skin, or out of the warp, or out of the woof;

⁵⁷and if it appears again in the garment, either in the warp, or in the woof, or in anything of skin, it is spreading. You shall burn what the plague is in with fire.

⁵⁸The garment, either the warp, or the woof, or whatever thing of skin it is, which you shall wash, if the plague has departed from them, then it shall be washed the second time, and it will be clean.”

⁵⁹This is the law of the plague of mildew in a garment of wool or linen, either in the warp, or the woof, or in anything of skin, to pronounce it clean, or to pronounce it unclean.
