Leviticus 13:57-59

Modern English Version

⁵⁷ If it still appears in the garment, either in the warp or in the woof, or in anything of leather, it is spreading. You shall burn in the fire that in which the disease appears. ⁵⁸ The garment that you have washed, either in the warp or woof, or anything of leather, if the disease is gone from it, then it shall be washed a second time and shall be clean.

⁵⁹ This is the law of the leprous disease in a garment of wool or linen, either in the warp or woof, or anything of leather to determine if it is clean or unclean.
