When a man has a rising in the skin of his flesh, or a scab or bright spot, and it is in the skin of his flesh like the plague of leprosy, then he shall be brought to Aaron the priest, or to one of his sons the priests.
And the priest shall look on the plague in the skin of the flesh. And if the hair in the plague has turned white, and the plague in sight is deeper than the skin of his flesh, it is a plague of leprosy. And the priest shall look on him and shall pronounce him unclean.
