2 Kings 5:10-14

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. Are not Abanah and Pharpar, the 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. And his servants came near, and spake unto him, and said, My father, if the prophet had bid thee do some great thing, wouldest thou not have done it? how much rather then, when he saith to thee, Wash, and be clean? Then went he down, and dipped himself seven times in the Jordan, according to the saying of the man of God; and his flesh came again like unto the flesh of a little child, and he was clean.
