Leviticus 13:29-31

New International Version

²⁹ “If a man or woman has a sore on their head^(A) or chin, ³⁰ the priest is to examine the sore, and if it appears to be more than skin deep and the hair in it is yellow and thin, the priest shall pronounce them unclean; it is a defiling skin disease on the head or chin. ³¹ But if, when the priest examines the sore, it does not seem to be more than skin deep and there is no black hair in it, then the priest is to isolate the affected person for seven days.^(B)
