Leviticus 13:57-59

New Catholic Bible

⁵⁷ But if it reappears on the garment, whether in the weave or the knit or on anything made of skin, it is spreading. Whatever is infected shall be burned in the fire. ⁵⁸ The garment, whether of weave or knit or anything made of skin, that has been washed and no longer has the spot, shall be washed a second time and it will then be clean. ⁵⁹ These are the statutes concerning infections of leprosy upon garments, whether woolen or linen, woven or knitted, or on anything made of skin, on how to declare it clean or to declare it unclean.”
