Leviticus 13:43 (KJV)

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

And 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.

Then 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;

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

And the leper in whom the plague is, his clothes shall be rent, and his head bare, and he shall put a covering upon his upper lip, and shall cry, Unclean, unclean.
