When a man shall have in the skin of his flesh a rising, or a scab, or a bright spot, and it becomes in the skin of his flesh a leprous disease, 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 is dim, then the priest shall shut him up seven days.
