Leviticus 13:57-59

New International Version

⁵⁷ But if it reappears in the fabric, in the woven or knitted material, or in the leather article, it is a spreading mold; whatever has the mold must be burned. ⁵⁸ Any fabric, woven or knitted material, or any leather article that has been washed and is rid of the mold, must be washed again. Then it will be clean.”

⁵⁹ These are the regulations concerning defiling molds in woolen or linen clothing, woven or knitted material, or any leather article, for pronouncing them clean or unclean.
