2 Kings 5:9-12 NIV
So Naaman went with his horses and chariots and stopped at the door of Elisha’s house. Elisha sent a messenger to say to him, “Go, wash yourself seven times in the Jordan, and your flesh will be restored and you will be cleansed.”
But Naaman went away angry and said, “I thought that he would surely come out to me and stand and call on the name of the LORD his God, wave his hand over the spot and cure me of my leprosy. Are not Abana and Pharpar, the rivers of Damascus, better than all the waters of Israel? Couldn’t I wash in them and be cleansed?” So he turned and went off in a rage.
