'Leprous' in the Bible
he is a leprous man, he is unclean. The priest shall surely pronounce him unclean; his infection is on his head.
if the mark is greenish or reddish in the garment or in the leather, or in the warp or in the woof, or in any article of leather, it is a leprous mark and shall be shown to the priest.
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.
