Leviticus 13:57-59

New King James Version

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.

⁵⁹ “This is the law of the leprous plague in a garment of wool or linen, either in the warp or woof, or in anything made of leather, to pronounce it clean or to pronounce it unclean.”
