Leviticus 13:47-59

“When a garment has a mark of leprosy in it, whether it is a wool garment or a linen garment, [Jude 23; Rev 3:4] whether in woven or knitted material or in the warp (lengthwise strands) or woof (crosswise strands) of linen or of wool, or in a skin or on anything made of leather, if the mark is greenish or reddish in the garment or in the leather or in the warp or woof or in any article made of leather, it is an infestation of leprosy and shall be shown to the priest. The priest shall examine the mark and shall quarantine the article with the mark for seven days. He shall examine the mark on the seventh day; if it has spread in the garment, whether in the warp or the woof, or in the leather, whatever the leather’s purpose, the mark is a malignant leprosy; it is unclean. So he shall burn the garment, whether the warp or woof, in wool or linen, or on anything made of leather in which the mark occurs; for it is a malignant leprosy; it shall be burned in the fire. “But if the priest sees that the mark has not spread in the garment, either in the warp or the woof, or on anything made of leather, then the priest shall order that they wash the thing in which the mark occurs, and he shall quarantine it for seven more days. The priest shall examine the article with the mark after it has been washed, and if the mark has not changed color, even though the mark has not spread, it is unclean; you shall burn it in the fire; it is a corroding mildew, whether on the top or on the front of it. “If the priest looks and the mark has faded after it is washed, he shall tear it out of the garment, or the leather, or out of the warp or woof. If it still appears in the garment, either in the warp or in the woof, or on anything made of leather, it is an outbreak; you shall burn the marked part in the fire. The garment, whether the warp or the woof, or anything made of leather from which the mildew has departed after washing, shall then be washed a second time and it will be [ceremonially] clean.” This is the law for a leprous disease in a garment of wool or linen, either in the warp or woof, or on anything made of leather, to pronounce it clean or unclean.
