2 Kings 5:9-15

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.” Naaman became angry and left. He said, “I thought Elisha would surely come out and stand before me and call on the name of the LORD his God. I thought he would wave his hand over the place and heal the disease. 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. Naaman’s servants came near and said to him, “My father, if the prophet had told you to do some great thing, wouldn’t you have done it? Doesn’t it make more sense just to do it? After all, he only told you, ‘Wash, and you will be clean.’ ” So Naaman went down and dipped in the Jordan seven times, just as Elisha had said. Then his skin became new again, like the skin of a child. And he was clean. Naaman and all his group returned to Elisha. He stood before Elisha and said, “Look, I now know there is no God in all the earth except in Israel. Now please accept a gift from me.”
