Leviticus 13:9-11

New International Version

⁹ “When anyone has a defiling skin disease, they must be brought to the priest. ¹⁰ The priest is to examine them, and if there is a white swelling in the skin that has turned the hair white and if there is raw flesh in the swelling, ¹¹ it is a chronic skin disease^(A) and the priest shall pronounce them unclean. He is not to isolate them, because they are already unclean.
