Leviticus 13:47-52

“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.
