Leviticus 13:29-46

And when a man or woman hath a plague upon the head or upon the beard, then the priest shall look on the plague; and, behold, if the appearance thereof be deeper than the skin, and there be in it yellow thin hair, then the priest shall pronounce him unclean: it is a scall, it is leprosy of the head or of the beard. And if the priest look on the plague of the scall, and, behold, the appearance thereof be not deeper than the skin, and there be no black hair in it, then the priest shall shut up him that hath the plague of the scall seven days: and in the seventh day the priest shall look on the plague; and, behold, if the scall be not spread, and there be in it no yellow hair, and the appearance of the scall be not deeper than the skin, then he shall be shaven, but the scall shall he not shave; and the priest shall shut up him that hath the scall seven days more: and in the seventh day the priest shall look on the scall; and, behold, if the scall be not spread in the skin, and the appearance thereof be not deeper than the skin; then the priest shall pronounce him clean: and he shall wash his clothes, and be clean. But if the scall spread abroad in the skin after his cleansing, then the priest shall look on him; and, behold, if the scall be spread in the skin, the priest shall not seek for the yellow hair; he is unclean. But if in his eyes the scall be at a stay, and black hair be grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean. And when a man or a woman hath in the skin of the flesh bright spots, even white bright spots; then the priest shall look; and, behold, if the bright spots in the skin of their flesh be of a dull white, it is a tetter, it hath broken out in the skin; he is clean. And if a man’s hair be fallen off his head, he is bald; yet is he clean. And if his hair be fallen off from the front part of his head, he is forehead bald; yet is he clean. But if there be in the bald head, or the bald forehead, a reddish-white plague; it is leprosy breaking out in his bald head, or his bald forehead. Then the priest shall look upon him; and, behold, if the rising of the plague be reddish-white in his bald head, or in his bald forehead, as the appearance of leprosy in the skin of the flesh; he is a leprous man, he is unclean: the priest shall surely pronounce him unclean; his plague is in his head. And the leper in whom the plague is, his clothes shall be rent, and the hair of his head shall go loose, and he shall cover his upper lip, and shall cry, Unclean, unclean. All the days wherein the plague is in him he shall be unclean; he is unclean: he shall dwell alone; without the camp shall his dwelling be.
