Leviticus 13:28-30

American Standard Version

²⁸ And if the bright spot stay in its place, and be not spread in the skin, but be dim; it is the rising of the burning, and the priest shall pronounce him clean: for it is the scar of the burning.

²⁹ And when a man or woman hath a plague upon the head or upon the beard, ³⁰ then the priest shall look on the plague; and, behold, if the appearance thereof be deeper than the skin, and there be in it yellow thin hair, then the priest shall pronounce him unclean: it is a scall, it is leprosy of the head or of the beard.
