2 Kings 5:11-13

11And Naaman was wroth, and went away and said, Behold, I thought, He will certainly come out to me, and stand, and call on the name of Jehovah his 1God, and wave his hand over the place, and cure the leper.

12Are not the Abanah and the Pharpar, rivers of Damascus, better than all the waters of Israel? may I not wash in them and be clean? And he turned and went away in a rage.

13And his servants drew near, and spoke to him and said, My father, [if] the prophet had bidden thee [do some] great thing, wouldest thou not have done it? how much rather then, when he says to thee, Wash and be clean?
