Vayikra 13:58-59

Orthodox Jewish Bible

⁵⁸ And the garment, either warp, or woof, or whatsoever thing of leather it be, which thou shalt wash, if the nega be departed from them, then it shall be washed the second time, and shall be tahor.

⁵⁹ This is the torah of the nega tzara’at in a garment of wool or linen, either in the warp, or woof, or any thing of leather, to pronounce it tahor, or to pronounce it tamei.
