2 Kings 5:11

But Naaman was wroth, which shows in what state of mind he had come to Samaria, as the proud general demanding aid, not as a suppliant pleading for help, and went away, and said, Behold, I thought, He will surely come out to me, and stand, and call on the name of the Lord, his God, and strike his hand over the place, moving it back and forth over the infected spot with a gesture of conjuring, and recover the leper. He thought such religious ceremonies, together with some application of magic, were essential, especially in his case.
