2 Kings 5:9-15

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. Naaman’s servants went to him and said, “My father, if the prophet had told you to do some great thing, would you not have done it? How much more, then, when he tells you, ‘Wash and be cleansed’!” So he went down and dipped himself in the Jordan seven times, as the man of God had told him, and his flesh was restored and became clean like that of a young boy. Then Naaman and all his attendants went back to the man of God. He stood before him and said, “Now I know that there is no God in all the world except in Israel. So please accept a gift from your servant.”
