Leviticus 13:57-59

English Standard Version Anglicised

⁵⁷ Then if it appears again in the garment, in the warp or the woof, or in any article made of skin, it is spreading. You shall burn with fire whatever has the disease. ⁵⁸ But the garment, or the warp or the woof, or any article made of skin from which the disease departs when you have washed it, shall then be washed a second time, and be clean.”

⁵⁹ This is the law for a case of leprous disease in a garment of wool or linen, either in the warp or the woof, or in any article made of skin, to determine whether it is clean or unclean.
