Adam Clarke Bible Commentary

If thou wilt be a servant unto this people - This is a constitutional idea of a king: he is the servant, but not the slave of his people; every regal act of a just king is an act of service to the state. The king is not only the fountain of law and justice; but as he has the appointment of all officers and judges, consequently he is the executor of the laws; and all justice is administered in his name. Properly speaking, a good and constitutional king is the servant of his people; and in being such he is their father and their king. They will be thy servants for ever - The way to insure the obedience of the people is to hold the reins of empire with a steady and impartial hand; let the people see that the king lives for them, and not for himself; and they will obey, love, and defend him. The state is maintained on the part of the ruler and the ruled by mutual acts of service and benevolence. A good king has no self-interest; and such a king will ever have obedient and loving subjects. The haughty, proud tyrant will have a suspicious and jealous people, hourly ripening for revolt. The king is made for the people, not the people for the king. Let every potentate wisely consider this; and let every subject know that the heaviest cares rest on the heart, and the heaviest responsibility rests on the head, of the king. Let them therefore, under his government, fashion themselves as obedient children; acknowledge him their head; and duly consider whose authority he has; that they may love, honor and obey him. Happy are the people who have such a king; safe is the king who has such a people.
