Leviticus 13:2-4

Revised Standard Version Catholic Edition

² “When a man 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, then he shall be brought to Aaron the priest or to one of his sons the priests, ³ and the priest shall examine the diseased spot on the skin of his body; and if the hair in the diseased spot has turned white and the disease appears to be deeper than the skin of his body, it is a leprous disease; when the priest has examined him he shall pronounce him unclean. ⁴ But if the spot is white in the skin of his body, and appears no deeper than the skin, and the hair in it has not turned white, the priest shall shut up the diseased person for seven days;
