2 Kings 5:9-12

9So Naaman came with his horses and chariots and stood at the door of Elisha’s house.

10Then Elisha sent him a messenger, who said, “Go and wash yourself seven times in the Jordan, and your flesh will be restored, and you will be clean.”

11But Naaman went away angry, saying, “I thought that he would surely come out, stand and call on the name of the LORD his God, and wave his hand over the spot to cure my leprosy. 12Are not the Abanah and Pharpar, the rivers of Damascus, better than all the waters of Israel? Could I not have washed in them and been cleansed?” So he turned and went away in a rage.
