'Wash' in the Bible

Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? do I not wash in them and I have been clean?' and he turneth and goeth on in fury.

And his servants come nigh, and speak unto him, and say, 'My father, a great thing had the prophet spoken unto thee -- dost thou not do it? and surely, when he hath said unto thee, Wash, and be clean.'
