Leviticus 13:47–59

^47–58“If clothing—woolen or linen clothing, woven or knitted cloth of linen or wool, leather or leatherwork—is infected with a patch of serious fungus and if the spot in the clothing or the leather or the woven or the knitted material or anything made of leather is greenish or rusty, that is a sign of serious fungus. Show it to the priest. The priest will examine the spot and then confiscate the material for seven days. On the seventh day he will reexamine the spot. If it has spread in the garment—the woven or knitted or leather material—it is the spot of a persistent serious fungus and the material is unclean. He must burn the garment. Because of the persistent and contaminating fungus, the material must be burned. But if when the priest examines it the spot has not spread in the garment, the priest will command the owner to wash the material that has the spot, and he will confiscate it for another seven days. He’ll then make another examination after it has been washed; if the spot hasn’t changed in appearance, even though it hasn’t spread, it is still unclean. Burn it up, whether the fungus has affected the back or the front. If, when the priest makes his examination, the spot has faded after it has been washed, he is to tear the spot from the garment. But if it reappears, it is a fresh outbreak—throw whatever has the spot in the fire. If the garment is washed and the spot has gone away, then wash it a second time; it is clean.

⁵⁹“These are the instructions regarding a spot of serious fungus in clothing of wool or linen, woven or knitted material, or any article of leather, for pronouncing them clean or unclean.”
