Leviticus 13:29-31

New American Standard Bible

²⁹ “Now if a man or woman has an infection on the head or on the beard, ³⁰ then the priest shall look at the infection, and if it appears to be deeper than the skin and there is thin yellowish hair in it, then the priest shall pronounce him unclean; it is a scale, it is leprosy of the head or of the beard. ³¹ But if the priest looks at the infection of the scale, and indeed, it appears to be no deeper than the skin and there is no black hair in it, then the priest shall ^[a]isolate the person with the scaly infection for seven days.
