2 Kings 5:9-10, 12

So Naaman came with his horses and chariots and stopped at the entrance of Elisha’s house. Elisha sent a messenger to him, saying, “Go and wash in the Jordan seven times, and your flesh will be restored to you and you will be clean.”

Are not Abana and Pharpar, the rivers of Damascus [in Aram], better than all the waters of Israel? Could I not wash in them and be clean?” So he turned and went away in a rage.
