Leviticus 13:44-46

he is a diseased man. He is unclean. The priest must surely pronounce him unclean because of his infection on his head. “As for the diseased person who has the infection, his clothes must be torn, the hair of his head must be unbound, he must cover his mustache, and he must call out ‘Unclean! Unclean!’ The whole time he has the infection he will be continually unclean. He must live in isolation, and his place of residence must be outside the camp.
