Leviticus

⁴⁰And if a man's hair be fallen off his head, he is bald; yet is he clean. ⁴¹And if his hair be fallen off from the front part of his head, he is forehead bald; yet is he clean. ⁴²But 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. ⁴³Then 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; ⁴⁴he is a leprous man, he is unclean: the priest shall surely pronounce him unclean; his plague is in his head. ⁴⁵And 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. ⁴⁶All 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.
