2 Kings 5
13 Ref 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.'
14 Ref 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.
