Leviticus 13:11

it is a chronic leprous disease in the skin of his body , and the priest shall pronounce him unclean . He shall not shut him up, for he is unclean .

it is a chronic skin disease and the priest shall pronounce them unclean. He is not to isolate them, because they are already unclean.

It is an old leprosy in the skin of his flesh, and the priest shall pronounce him unclean, and shall not shut him up: for he is unclean.
