II Kings 5:12-14

Are not the Abanah and the Pharpar, the rivers of Damascus, better than all the waters of Israel? Could I not wash in them and be clean?” So he turned and went away in a rage. And his servants came near and spoke to him, and said, “My father, if the prophet had told you to do something great, would you not have done it? How much more then, when he says to you, ‘Wash, and be clean’?” So he went down and dipped seven times in the Jordan, according to the saying of the man of God; and his flesh was restored like the flesh of a little child, and he was clean.
