Leviticus 13:29-31

New Century Version

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.
