Leviticus 13:43-45

New Century Version

⁴³ A priest must look at that person. If the swelling of the sore on his bald head or forehead is red-white, like a skin disease that spreads, ⁴⁴ that person has a skin disease. He is unclean. The priest must announce that the person is unclean because of the sore on his head.

⁴⁵ “If a person has a skin disease that spreads, he must warn other people by shouting, ‘Unclean, unclean!’ His clothes must be torn at the seams, he must let his hair stay uncombed, and he must cover his mouth.
