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