2 Kings 5:13-14

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.
