Leviticus 13:57

Then if it appears again in the garment , in the warp or the woof , or in any article made of skin , it is spreading . You shall burn with fire whatever has the disease .

But if it reappears in the fabric, in the woven or knitted material, or in the leather article, it is a spreading mold; whatever has the mold must be burned.

And if it appear still in the garment, either in the warp, or in the woof, or in any thing of skin; it is a spreading plague : thou shalt burn that wherein the plague is with fire.
