Leviticus 13:24-28 - A Burn On The Skin
24 “Or if the body has on its skin a burn from fire and the new flesh of the burn becomes a bright spot, reddish white or white, 25 then the priest shall examine it, and if the hair in the bright spot has turned white, and it appears deeper than the skin, then leprosy has broken out in the burn. So the priest shall pronounce him unclean; it is the disease of leprosy. 26 But if the priest examines it and there is no white hair in the bright spot and it is not deeper than [the rest of] the skin but is dull in color, then the priest shall isolate him for seven days. 27 And the priest shall examine him on the seventh day; if it is spreading farther on the skin, then the priest shall pronounce him unclean; it is leprosy. 28 But if the bright spot remains in its place and has not spread in the skin, but is dull in color, it is a swelling from the burn, and the priest shall pronounce him clean; for it is the scar of the burn.
