17. Rejoice not when thine enemy falleth, and let not thine heart be glad when he is overthrown:
18. Lest the LORD see it, and it displease him, and he turn away his wrath from him.
19. Fret not thyself because of evil-doers; neither be thou envious at the wicked:
20. For there will be no reward to the evil man; the lamp of the wicked shall be put out.
21. My son, fear thou the LORD and the king: and meddle not with them that are given to change:
22. For their calamity shall rise suddenly; and who knoweth the destruction of them both?
