'Clean' in the Bible

Now a leper came to him and fell to his knees, asking for help. "If you are willing, you can make me clean," he said.

Moved with compassion, Jesus stretched out his hand and touched him, saying, "I am willing. Be clean!"

The leprosy left him at once, and he was clean.

For it does not enter his heart but his stomach, and then goes out into the sewer." (This means all foods are clean.)
