“When a person has on the skin of his body a swelling or an eruption or a spot and it turns into a defiling disease on the skin of his body, he shall be brought to Aaron the priest or to one of his sons the priests.
But if the priest examines it and the hair in the spot is not white and it is no deeper than the skin but has abated, the priest shall confine him seven days.
But if the spot remains in one place and does not spread in the skin but has abated, it is a swelling from the burn, and the priest shall pronounce him clean, for it is the scar of the burn.
