Leviticus 13:41

37But if the scall be in his sight at a stay, and that there is black hair grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean.

38If a man also or a woman have in the skin of their flesh bright spots, even white bright spots;

39Then the priest shall look: and, behold, if the bright spots in the skin of their flesh be darkish white; it is a freckled spot that groweth in the skin; he is clean.

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.

45And 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.
