Leviticus 13
2 Ref "When a man shall have a rising in his body's skin, or a scab, or a bright spot, and it becomes in the skin of his body the plague of leprosy, then he shall be brought to Aaron the priest, or to one of his sons the priests:
3 Ref and the priest shall examine the plague in the skin of the body: and if the hair in the plague has turned white, and the appearance of the plague is deeper than the body's skin, it is the plague of leprosy; and the priest shall examine him, and pronounce him unclean.
