God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
There are limits prescribed by God to [the king’s] power, within which they ought to be satisfied: namely to work for the common good and to govern and direct the people in truest fairness and justice; not to be puffed up with their own importance, but to remember that they also are subjects of God.
