'Clean' in the Bible

and Elisha sendeth unto him a messenger, saying, 'Go, and thou hast washed seven times in Jordan, and thy flesh doth turn back to thee -- and be thou clean.

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.'

And he goeth down and dippeth in Jordan seven times, according to the word of the man of God, and his flesh doth turn back as the flesh of a little youth, and is clean.
