Leviticus 13:43-46

⁴³Then the priest shall examine him. Behold, if the swelling of the plague is reddish-white in his bald head, or in his bald forehead, like the appearance of leprosy in the skin of the body,

⁴⁴he is a leprous man. He is unclean. The priest shall surely pronounce him unclean. His plague is on his head.

⁴⁵“The leper in whom the plague is shall wear torn clothes, and the hair of his head shall hang loose. He shall cover his upper lip, and shall cry, ‘Unclean! Unclean!’

⁴⁶All the days in which the plague is in him he shall be unclean. He is unclean. He shall dwell alone. His dwelling shall be outside of the camp.
