2 Kings 5:10-14

Elisha sent a messenger to him, saying, “Go and wash in the Jordan seven times, and your flesh will be restored to you and you will be clean.” But Naaman was furious and went away and said, “Indeed! I thought ‘He would at least come out to [see] me and stand and call on the name of the LORD his God, and wave his hand over the place [of leprosy] and heal the leper.’ Are not Abana and Pharpar, the rivers of Damascus [in Aram], better than all the waters of Israel? Could I not wash in them and be clean?” So he turned and went away in a rage. Then his servants approached and said to him, “My father, if the prophet had told you to do some great thing, would you not have done it? How much more then, when he has said to you, ‘Wash, and be clean?’ ” So he went down and plunged himself into the Jordan seven times, just as the man of God had said; and his flesh was restored like that of a little child and he was clean.
