17 Rejoice not when your enemy falls, and let not your heart be glad when he stumbles:
18 Lest the LORD sees it, and it displeases him, and he turns away his wrath from him.
19 Fret not yourself because of evil men, neither be you envious at the wicked;
20 For there shall be no reward to the evil man; the lamp of the wicked shall be put out.
21 My son, fear the LORD and the king: and associate not with them that are given to change:
22 For their calamity shall rise suddenly; and who knows the ruin of them both?
23 These things also belong to the wise. It is not good to have partiality in judgment.
