What did a person with a skin disease have to cry out, according to Leviticus 13?

Answer: "Unclean, unclean!"

A diseased person wore torn clothes, covered his mouth, cried "Unclean, unclean!" and lived alone outside the camp.

“A diseased person must wear torn clothes and let his hair hang loose, and he must cover his mouth and cry out, ‘Unclean, unclean!’ As long as he has the infection, he remains unclean. He must live alone in a place outside the camp.”— Leviticus 13:45-46 (BSB)
