Leviticus 13:26-28

Complete Jewish Bible

²⁶ But if the cohen examines it and sees no white hair in the bright spot, and it is no lower than the skin around it but looks faded, then the cohen is to isolate him for seven days. ²⁷ On the seventh day the cohen is to examine him; if it has spread on the skin, then the cohen is to declare him unclean; it is a sore from tzara‘at. ²⁸ But if the bright spot stays where it was and has not spread on the skin but appears faded, it is a swelling due to the burn; and the cohen is to declare him clean; because it is only a scar from the burn.
