Leviticus 13:56-58

New King James Version

⁵⁶ If the priest examines it, and indeed the plague has faded after washing it, then he shall tear it out of the garment, whether out of the warp or out of the woof, or out of the leather. ⁵⁷ But if it appears again in the garment, either in the warp or in the woof, or in anything made of leather, it is a spreading plague; you shall burn with fire that in which is the plague. ⁵⁸ And if you wash the garment, either warp or woof, or whatever is made of leather, if the plague has disappeared from it, then it shall be washed a second time, and shall be clean.
