Webster(i)
51 And he shall look on the plague on the seventh day: if the plague is 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.
52 He shall therefore burn that garment, whether warp or woof, in woolen or in linen, or any thing of skin, in which the plague is: for it is a fretting leprosy; it shall be burnt in the fire.
