Leviticus 13:51

Then he shall examine the disease on the seventh day . If the disease has spread in the garment , in the warp or the woof , or in the skin , whatever be the use of the skin , the disease is a persistent leprous disease ; it is unclean .

On the seventh day he is to examine it, and if the mold has spread in the fabric, the woven or knitted material, or the leather, whatever its use, it is a persistent defiling mold; the article is unclean.

And he shall look on the plague on the seventh day : if the plague be spread in the garment, either in the warp, or in the woof, or in a skin, or in any work that is made of skin; the plague is a fretting leprosy; it is unclean.
