'Clean' in the Bible

Then a man with a serious skin disease came to Him and, on his knees, begged Him: “If You are willing, You can make me clean.”

Moved with compassion, Jesus reached out His hand and touched him. “I am willing,” He told him. “Be made clean.”

For it doesn’t go into his heart but into the stomach and is eliminated.” (As a result, He made all foods clean.)
