Leviticus 13:47-52

Regulations About Defiling Molds 47“As for any fabric that is spoiled with a defiling mold—any woolen or linen clothing, 48any woven or knitted material of linen or wool, any leather or anything made of leather— 49if the affected area in the fabric, the leather, the woven or knitted material, or any leather article, is greenish or reddish, it is a defiling mold and must be shown to the priest. 50The priest is to examine the affected area and isolate the article for seven days. 51On the seventh day he is to examine it, and if the mold has spread in the fabric, the woven or knitted material, or the leather, whatever its use, it is a persistent defiling mold; the article is unclean.

52He must burn the fabric, the woven or knitted material of wool or linen, or any leather article that has been spoiled; because the defiling mold is persistent, the article must be burned.
