“When a person has on the skin of his body a swelling or an eruption or a spot and it turns into a defiling disease on the skin of his body, he shall be brought to Aaron the priest or to one of his sons the priests.
The priest shall examine him again on the seventh day, and if the disease has abated and the disease has not spread in the skin, the priest shall pronounce him clean; it is only an eruption, and he shall wash his clothes and be clean.
