Leviticus 13:51-52

51He shall then look at the mark on the seventh day; if the mark has spread in the garment, whether in the 1warp or in the woof, or in the leather, whatever the purpose for which the leather is used, the mark is a 2leprous malignancy, it is unclean. 52So he shall burn the garment, whether it is the 3warp or the woof, in wool or in linen, or any article of leather, in which the mark occurs; for it is a 4leprous malignancy. It shall be burned in the fire.
