“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 24:19-22 (KJV)
