Proverbs 21:11-13

The Voice

¹¹ A naive person wises up when he sees a mocker punished.
    A wise person becomes even wiser just by being instructed.
¹² The right-living understands how evildoers operate;
    he subverts them and ruins their plans.
¹³ If you ignore the groans of the poor,
    one day your own cries for help will go unanswered.
