Proverbs 21:10-12

The Voice

¹⁰ Wicked people delight in doing bad things;
    their neighbors never see even a hint of compassion.
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.
