Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? may I not be washed in them and become clean? So turning, he went away in wrath.

Then his servants came to him and said, If the prophet had given you orders to do some great thing, would you not have done it? how much more then, when he says to you, Be washed and become clean?

Then he went down seven times into the waters of Jordan, as the man of God had said; and his flesh became like the flesh of a little child again, and he was clean.

And over Jerusalem will be stretched the line of Samaria and the weight of Ahab; Jerusalem will be washed clean as a plate is washed, and turned over on its face.
