Mercy and truth preserve the king. — See above on Proverbs 3:3. The love and faithfulness he shows to his subjects draw out the same qualities in them, and these are the safeguard of his throne. So (Psalms 130:4) the mercy shown by God inspires man with a reverent fear of Him, while harshness might have made him a slave, or driven him through despair into rebellion. (Comp. Jeremiah 33:9.)
