17Rejoice not when thine enemy falleth, and let not thy heart be glad when he stumbleth;
18lest Jehovah see it, and it be evil in his sight, and he turn away his anger from him.
19Fret not thyself because of evil-doers, and be not envious of the wicked:
20for there shall be no future to the evil man; the lamp of the wicked shall be put out.
21My son, fear Jehovah and the king: meddle not with them that are given to change.
22For their calamity shall rise suddenly; and who knoweth the ruin of them both?
