And the priest shall examine him on the seventh day, and if it has spread around the skin, then the priest shall pronounce him unclean. It is a leprous sore.
When a man has on the skin of his body a swelling, a scab, or spot, and it turns on the skin of his body like a mark of a leprous sore, then he shall be brought to Aaron the priest or to one of his sons the priests.
But if the priest looks at it, and there is no white hair in the spot, and it is no deeper than the other skin and is faded, then the priest shall isolate him for seven days.
If the spot stays in its place and it does not spread in the skin, but is faded, then it is a swelling from the burn, and the priest shall pronounce him clean, for it is a scar from the burn.
