¹⁵ Correction and punishment make children wise,
    but those left alone will disgrace their mother.

¹⁷ Correct your children, and you will be proud;
    they will give you satisfaction.

¹⁹ Words alone cannot correct a servant,
    because even if they understand, they won’t respond.

²¹ If you spoil your servants when they are young,
    they will bring you grief later on.
