²⁰ A wise child brings joy to a father,
    but fools despise their mothers.
²¹ Folly is joy to those who lack sense,
    but those with understanding walk straight ahead.

²¹ Having a fool for a son brings grief;
    there’s no joy for a scoundrel’s father.

²⁵ A foolish son is irritating to his father
    and bitter to her who gave birth to him.

¹⁵ My child, if your heart is wise,
    then my heart too will be happy.
¹⁶ My inner being will rejoice
    when your lips speak with integrity.
