'Malignancy' in the Bible

He shall then look at the mark on the seventh day; if the mark has spread in the garment, whether in the warp or in the woof, or in the leather, whatever the purpose for which the leather is used, the mark is a leprous malignancy, it is unclean.

So he shall burn the garment, whether the warp or the woof, in wool or in linen, or any article of leather in which the mark occurs, for it is a leprous malignancy; it shall be burned in the fire.
