Modern English Version

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.
