‘Whatever man of the descendants of Aaron, who is a leper or has a discharge, shall not eat the holy offerings until he is clean. And whoever touches anything made unclean by a corpse, or a man who has had an emission of semen,
everything that can endure fire, you shall put through the fire, and it shall be clean; and it shall be purified with the water of purification. But all that cannot endure fire you shall put through water.
