2 Kings 5:13-14

But Naaman’s servants came near and talked to him. They said, “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. He did just as Elisha had said. Then Naaman’s skin became new again. It was like the skin of a little boy. And Naaman was clean!
