Leviticus 13:42

40And the man whose hair is fallen off his head, he is bald; yet is he clean.

41And he that hath his hair fallen off from the part of his head toward his face, he is forehead bald: yet is he clean.

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.
