Leviticus 13:42-44

42And if there be in the bald head, or bald forehead, a white reddish sore; it is a leprosy sprung up in his bald head, or his bald forehead.

43Then the priest shall look upon it: and, behold, if the rising of the sore be white reddish in his bald head, or in his bald forehead, as the leprosy appeareth in the skin of the flesh;

44He is a leprous man, he is unclean: the priest shall pronounce him utterly unclean; his plague is in his head.
