“Rejoice not when thine enemy falleth, and let not thine heart be glad when he stumbleth: lest the LORD see it, and it displease Him, and He turn away His wrath from him.
Fret not thyself because of evil men, neither be thou envious at the wicked; for there shall be no reward to the evil man; the candle of the wicked shall be put out.
My son, fear thou the LORD and the king: and meddle not with them that are given to change: for their calamity shall rise suddenly; and who knoweth the ruin of them both?” Proverbs 24:17-22 (KJV)
