Leviticus 13:30 in the King James Version
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.
Context
29 “When a man or woman has a plague on the head or on the beard,
30 then the priest shall examine the plague; and behold, if its appearance is deeper than the skin, and the hair in it is yellow and thin, then the priest shall pronounce him unclean. It is an itch. It is leprosy of the head or of the beard.
31 If the priest examines the plague of itching, and behold, its appearance isn’t deeper than the skin, and there is no black hair in it, then the priest shall isolate the person infected with itching seven days.
