Leviticus 13:26-28

New International Version

²⁶ But if the priest examines it and there is no white hair in the spot and if it is not more than skin deep and has faded, then the priest is to isolate them for seven days.^{(A) 27} On the seventh day the priest is to examine that person,^(B) and if it is spreading in the skin, the priest shall pronounce them unclean; it is a defiling skin disease. ²⁸ If, however, the spot is unchanged and has not spread in the skin but has faded, it is a swelling from the burn, and the priest shall pronounce them clean; it is only a scar from the burn.^(C)
