Any man of the seed of Aaron that is leprous or has a flow, he shall not eat of the holy things until he is clean; he who touches any uncleanness of a person, or a man who has an emission of semen go out of him;
everything that passes through the fire, you shall make it go through the fire; and it shall be clean. Only it shall be purified with the water for impurity. And every thing that cannot go through the fire, you shall make go through the water.
