'Clean' in the Bible

And there cometh to him a leper, beseeching him, and kneeling down to him, and saying unto him, If thou wilt, thou canst make me clean.

And being moved with compassion, he stretched forth his hand, and touched him, and saith unto him, I will; be thou made clean.

And straightway the leprosy departed from him, and he was made clean.

because it goeth not into his heart, but into his belly, and goeth out into the draught? This he said , making all meats clean.
