Proverbs 21:11-13

Common English Bible

¹¹ When a mocker is punished, the naive person gains wisdom;
    when insight comes to the wise, knowledge increases.
¹² The righteous one observes the house of the wicked,
    turning the wicked toward trouble.
¹³ Those who close their ears to the cries of the poor
    will themselves call out but receive no answer.
