'Wool' in the Bible
“When a garment has a mark of leprosy in it, whether it is a wool garment or a linen garment,
whether in warp or woof, of linen or of wool, whether in leather or in any article made of leather,
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.
This is the law for the mark of leprosy in a garment of wool or linen, whether in the warp or in the woof, or in any article of leather, for pronouncing it clean or unclean.
