Leviticus 13:42-44

42And if there is in the bald head, or bald forehead, a white reddish sore; it is a leprosy sprung up on his bald head, or his bald forehead. 43Then the priest shall look upon it: and, behold, if the swelling of the sore is white reddish on his bald head, or on 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.
