Leviticus 13:51-52

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. And he shall burn the garment, or the warp or the woof, the wool or the linen, or any article made of skin that is diseased, for it is a persistent leprous disease. It shall be burned in the fire.
