Leviticus 13:21-31

21 But if the priest looks at the spot and there are no white hairs in it and the spot is not deeper than the skin and it has faded, the priest must separate the person from other people for seven days.
22 If the spot spreads on the skin, the priest must announce that the person is unclean; it is a disease that will spread.
23 But if the bright spot does not spread or change, it is only the scar from the old boil. Then the priest must announce that the person is clean.
24 "When a person gets a burn on his skin, if the open sore becomes white or red,
25 the priest must look at it. If the white spot seems deeper than the skin and the hair at that spot has become white, it is a harmful skin disease. The disease has broken out in the burn, and the priest must announce that the person is unclean. It is a harmful skin disease.
26 But if the priest looks at the spot and there is no white hair in the bright spot, and the spot is no deeper than the skin and has faded, the priest must separate the person from other people for seven days.
27 On the seventh day the priest must look at him again. If the spot has spread on the skin, the priest must announce that the person is unclean. It is a harmful skin disease.
28 But if the bright spot has not spread on the skin but has faded, it is the swelling from the burn. The priest must announce that the person is clean, because the spot is only a scar from the burn.
29 "When a man or a woman gets a sore on the scalp or on the chin,
30 a priest must look at the sore. If it seems deeper than the skin and the hair around it is thin and yellow, the priest must announce that the person is unclean. It is an itch, a harmful skin disease of the head or chin.
31 But if the priest looks at it and it does not seem deeper than the skin and there is no black hair in it, the priest must separate the person from other people for seven days.
