2 Kings 5:8-11

And it was so, when Elisha the man of God heard that the king of Israel had rent his clothes, that he sent to the king, saying, Wherefore hast thou rent thy clothes? let him come now to me, and he shall know that there is a prophet in Israel. So Naaman came with his horses and with his chariots, and stood at the door of the house of Elisha. And Elisha sent a messenger unto him, saying, Go and wash in the Jordan seven times, and thy flesh shall come again to thee, and thou shalt be clean. But Naaman was wroth, and went away, and said, Behold, I thought, He will surely come out to me, and stand, and call on the name of Jehovah his God, and wave his hand over the place, and recover the leper.
