Proverbs 29:19-21

Young's Literal Translation

¹⁹ By words a servant is not instructed though he understand, And there is nothing answering.

²⁰ Thou hast seen a man hasty in his words! More hope of a fool than of him.

²¹ Whoso is bringing up his servant delicately, from youth, [At] his latter end also he is continuator.
