When a person has on the skin of his body a swelling or an eruption or a spot, and it turns into a leprous 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 the disease on the skin of his body, and if the hair in the diseased area has turned white and the disease appears to be deeper than the skin of his body, it is a leprous disease; after the priest has examined him he shall pronounce him ceremonially unclean.
