And the priest shall look upon him the seventh day. If it spread abroad in the skin, then the priest shall pronounce him unclean; it is a leprous disease.
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 is no white hair in the bright spot, and it is no lower than the skin, but is dim, then the priest shall shut him up seven days.
And if the bright spot stays in its place, and be not spread in the skin, but is dim, it is the rising of the burning, and the priest shall pronounce him clean, for it is the scar of the burning.
