17 Rejoice not when thine enemy falleth, and let not thy heart be glad when he stumbleth; 18 lest Jehovah see it, and it be evil in his sight, and he turn away his anger from him.
19 Fret not thyself because of evil-doers, [and] be not envious of the wicked: 20 for there shall be no future to the evil [man]; the lamp of the wicked shall be put out.
