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.
But if the priest looks on it, and, behold, there are no white hairs in it, and it is not lower than the skin, but has become dark, then the priest shall shut him up seven days.
