17 Don’t rejoice when your enemy falls.
Don’t let your heart be glad when he is overthrown; 18 lest Yahweh see it, and it displease him,
and he turn away his wrath from him.

19 Don’t fret yourself because of evildoers;
neither be envious of the wicked: 20 for there will be no reward to the evil man;
and the lamp of the wicked shall be snuffed out.
