17 Do not be glad at the fall of your hater, and let not your heart have joy at his downfall: 18 For fear that the Lord may see it, and it may be evil in his eyes, and his wrath may be turned away from him.
19 Do not be troubled because of evil-doers, or have envy of sinners: 20 For there will be no future for the evil man; the light of sinners will be put out.
