None of the line of Aaron who is a leper or suffers a discharge may eat of the holy things until he is clean. Whoever touches anything that is unclean through contact with the dead or a man who has had an emission of semen,
everything that can stand the fire, you shall pass through the fire, and it shall be clean. Nevertheless it shall also be purified with the water of impurity; and whatever cannot stand the fire, you shall pass through the water.
