2 Kings 5:9-10, 12

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

Are not Abana and Pharpar, the rivers of Damascus, 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.
