Proverbs 24:17-19

Complete Jewish Bible

¹⁷ Don’t rejoice when your enemy falls;
    don’t let your heart be glad when he stumbles.
¹⁸ For Adonai might see it, and it would displease him;
    he might withdraw his anger from your foe.

¹⁹ Don’t get upset because of evildoers;
    don’t be envious of the wicked.
