Leviticus 13:51

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

(New International Version)

'He shall then look at the mark on the seventh day; if the mark has spread in the garment, whether in the warp or in the woof, or in the leather, whatever the purpose for which the leather is used, the mark is a leprous malignancy, it is unclean.

(New American Standard Bible)

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.

(King James Version)
