Vayikra 13:48-50

Orthodox Jewish Bible

⁴⁸ Whether it be in the warp, or woof; of linen, or of wool; whether in a leather, or in anything made of leather;

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;
