Leviticus 13:26-28

Revised Standard Version

²⁶ But if the priest examines it, and the hair in the spot is not white and it is no deeper than the skin, but is dim, the priest shall shut him up seven days, ²⁷ and the priest shall examine him the seventh day; if it is spreading in the skin, then the priest shall pronounce him unclean; it is a leprous disease. ²⁸ But if the spot remains in one place and does not spread in the skin, but is dim, it is a swelling from the burn, and the priest shall pronounce him clean; for it is the scar of the burn.
