2 Kings 5:10, 12-13

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.”

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.’ ”
