2 Kings 5:9-12

   9: So Naaman came with his horses and with his chariot, and stood at the door of the house of Elisha.
   10: 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.
   11: 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 the LORD his God, and strike his hand over the place, and recover the leper.
   12: Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? may I not wash in them, and be clean? So he turned and went away in a rage.
