Leviticus 13:56-58

New Catholic Bible

⁵⁶ If the priest examines the garment and the spot has faded after the washing, then he shall tear it out of the garment, whether it be made of skin or woven or knitted. 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.
