Leviticus 13:44-46

44he is a leprous man, he is unclean. The priest shall surely pronounce him unclean; his infection is on his head.

45“As for the leper who has the infection, his clothes shall be torn, and 1the hair of his head shall be 2uncovered, and he shall 3cover his mustache and cry, ‘4Unclean! Unclean!’ 46He shall remain unclean all the days during which he has the infection; he is unclean. He shall live alone; his dwelling shall be 5outside the camp.
