2 Kings 5:12-14

Young's Literal Translation

¹² 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.

¹³ 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 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.
