2 Kings 5:9-10, 12

So Naaman went with his horses and chariots to Elisha’s house and stood outside the door. Elisha sent Naaman a messenger who said, “Go and wash in the Jordan River seven times. Then your skin will be healed, and you will be clean.”

The Abana and the Pharpar, the rivers of Damascus, are better than all the waters of Israel. Why can’t I wash in them and become clean?” So Naaman went away very angry.
