2 Kings 5:13-14

13His servants approached and said to him, “O master, if the prophet had told you to do some difficult task, you would have been willing to do it. It seems you should be happy that he simply said, “Wash and you will be healed.”

14So he went down and dipped in the Jordan seven times, as the prophet had instructed. His skin became as smooth as a young child’s and he was healed.
