Vayikra 13:49-51

Orthodox Jewish Bible

⁴⁹ And if the nega be greenish or reddish in the garment, or in the leather, either in the warp, or in the woof, or in any thing of leather, it is a nega tzara’at, and shall be shown unto the kohen;

⁵⁰ And the kohen shall examine the nega, and quarantine it that hath the nega shivat yamim;

⁵¹ And he shall examine the nega on the yom hashevi’i; if the nega be spread in the garment, either in the warp, or in the woof, or in a leather, or in any work that is made of leather, the nega is a malignant tzara’at; it is tamei.
