Proverbs 24:19-23

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?

These things also belong to the wise. It is not good to have respect of persons in judgment.
