Leviticus 13:51-52

51and 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 the skin, whatever service skin is used for; the plague is a fretting leprosy; it is unclean.

52And he shall burn the garment, whether the warp or the woof, in woollen or in linen, or any thing of skin, wherein the plague is: for it is a fretting leprosy; it shall be burnt in the fire.
