Leviticus 13:29-30

King James Version

²⁹ If a man or woman have a plague upon the head or the beard;

³⁰ Then the priest shall see the plague: and, behold, if it be in sight deeper than the skin; and there be in it a yellow thin hair; then the priest shall pronounce him unclean: it is a dry scall, even a leprosy upon the head or beard.
