Proverbs 16:10-12

Complete Jewish Bible

¹⁰ Divine inspiration is on the lips of the king,
    so his mouth must be faithful when he judges.
¹¹ The balance and scales of justice have their origin in Adonai;
    all the weights in the bag are his doing.
¹² It is an abomination for a king to do evil,
    for the throne is made secure by righteousness.
