¹⁵ The rod and reproof give wisdom,
    but a child left to himself brings his mother to shame.

¹⁷ Correct your son, and he will give you rest;
    yes, he will give delight to your soul.

¹⁹ A servant will not be corrected by words,
    for though he understands he will not answer.

²¹ He who delicately brings up his servant from a child
    will have him as a son in the end.
