I. That magistrates should do their duty in their places, and the powers answer the great ends for which they were ordained of God, v. 1, 2. 1. There shall be a king and princes that shall reign and rule; for it cannot go well when there is no king in Israel. The princes must have a king, a monarch over them as supreme, in whom they may unite; and the king must have princes under him as officers, by whom he may act, 1 Pet. ii. 13, 14. They both shall know their place and fill it up. The king shall reign, and yet, without any diminution to his just prerogative, the princes shall rule in a lower sphere, and all for the public good. 2. They shall use their power according to law, and not against it. They shall reign in righteousness and in judgment, with wisdom and equity, protecting the good and punishing the bad; and those kings and princes Christ owns as reigning by him who decree justice, Prov. viii. 15. Such a King, such a Prince, Christ himself is; he reigns by rule, and in righteousness will he judge the world, ch. ix. 7; xi. 4. 3. Thus they shall be great blessings to the people (v. 2): A man, that man, that king that reigns in righteousness, shall be as a hiding-place. When princes are as they should be people are as they would be. (1.) They are sheltered and protected from many mischiefs. This good magistrate is a covert to the subject from the tempest of injury and violence; he defends the poor and fatherless, that they be not made a prey of by the mighty. Whither should oppressed innocency flee, when blasted by reproach or borne down by violence, but to the magistrate as its hiding-place? To him it appeals, and by him it is righted. (2.) They are refreshed and comforted with many blessings. This good magistrate gives such countenance to those that are poor and in distress, and such encouragement to every thing that is praiseworthy, that he is as rivers of water in a dry place, cooling and cherishing the earth and making it fruitful, and as the shadow of a great rock, under which a poor traveller may shelter himself from the scorching heat of the sun in a weary land. It is a great reviving to a good man, who makes conscience of doing his duty, in the midst of contempt and contradiction, at length to be backed, and favoured, and smiled upon in it by a good magistrate. All this, and much more, the man Christ Jesus is to all the willing faithful subjects of his kingdom. When the greatest evils befal us, not only the wind, but the tempest, when storms of guilt and wrath beset us and beat upon us, they drive us to Christ, and in him we are not only safe, but satisfied that we are so; in him we find rivers of water for those that hunger and thirst after righteousness, all the refreshment and comfort that a needy soul can desire, and the shadow, not of a tree, which sun or rain may beat through, but of a rock, of a great rock, which reaches a great way for the shelter of the traveller. Some observe here that as the covert, and the hiding-place, and the rock, do themselves receive the battering of the wind and storm, to save those from it that take shelter in them, so Christ bore the storm himself to keep it off from us.
