2 Kings 5:13-14

13Naaman’s servants, however, approached him and said, “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 tells you, ‘Wash and be cleansed’?”

14So Naaman went down and dipped himself in the Jordan seven times, according to the word of the man of God, and his flesh was restored and became like that of a little child, and he was clean.
