Leviticus 13:47-52

47The garment also that the plague of leprosy is in, whether it be a woollen garment, or a linen garment; 48whether it be in warp, or woof; of linen, or of woollen; whether in a skin, or in anything made of skin; 49if the plague be greenish or reddish in the garment, or in the skin, or in the warp, or in the woof, or in anything of skin; it is the plague of leprosy, and shall be showed unto the priest. 50And the priest shall look upon the plague, and shut up that which hath the plague seven days: 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 anything of skin, wherein the plague is: for it is a fretting leprosy; it shall be burnt in the fire.
