And the priest shall look upon him the seventh day: and if it is spread much abroad in the skin, then the priest shall pronounce him unclean: it is the disease of leprosy.
When a man shall have in the skin of his flesh a swelling, a scab, or bright spot, and it be in the skin of his flesh like the disease of leprosy; then he shall be brought unto Aaron the priest, or unto one of his sons the priests:
But if the priest looks on it, and, behold, there be no white hair in the bright spot, and it is no lower than the other skin, but is somewhat dark; then the priest shall shut him up seven days:
And if the bright spot stays in its place, and spreads not in the skin, but it is somewhat dark; it is a swelling of the burn, and the priest shall pronounce him clean: for it is a scar from the burn.
