Leviticus 13:26-28

New Catholic Bible

²⁶ But if the priest examines it and there is no white hair on the spot and it is not deeper than the skin, but is a bit darker, then the priest shall quarantine him for seven days. ²⁷ On the seventh day the priest shall examine him again. If it has spread over the skin, then the priest shall pronounce him to be unclean. It is a leprous sore. ²⁸ But if the spot has remained where it was and it has not spread on the skin, but it is somewhat darker, then it is only the swelling of a burn. The priest shall declare him to be clean, because it is only the scar from a burn.
