Note, 1. National sins bring national disorders and the disturbance of the public repose: For the transgression of a land, and a general defection from God and religion to idolatry, profaneness, or immorality, many are the princes thereof, many at the same time pretending to the sovereignty and contending for it, by which the people are crumbled into parties and factions, biting and devouring one another, or many successively, in a little time, one cutting off another, as Kg1 16:8, etc., or soon cut off by the hand of God or of a foreign enemy, as Kg2 24:5, etc. As the people suffer for the sins of the prince,
Delirant reges, plectuntur Achivi -
Kings play the madmen, and their people suffer for it,
so the government sometimes suffers for the sins of the people. 2. Wisdom will prevent or redress these grievances: By a man, that is, by a people, of understanding, that come again to themselves and their right mind, things are kept in a good order, or, if disturbed, brought back to the old channel again. Or, By a prince of understanding and knowledge, a privy-counsellor, or minister of state, that will restrain or suppress the transgression of the land, and take the right methods of healing the state thereof, the good estate of it will be prolonged. We cannot imagine what a great deal of service one wise man may do to a nation in a critical juncture.

For the transgression of a land many are the princes thereof,.... Either together; that is, reigning princes, such as lay claim to the crown, and usurp it; otherwise it is a happiness to a nation to have many princes of the blood, to inherit in succession, to support the crown in their family, and defend a nation, and study the good of it; but it is a judgment to a nation when many rise up as competitors for rule, or do rule, as at Athens, where thirty tyrants sprung up at once; by which factions and parties are made, and which issue in oppression, rapine, and murder: or successively, very quickly, one after another, being dethroned the one by the other: or removed by death, as in the land of Israel, in the times of the judges, and of the kings of Israel and Judah, after the revolt of the ten tribes; which frequent changes produce different administrations, new laws, and fresh taxes, disagreeable to the people; and oftentimes children come to be their princes, which is always reckoned an infelicity to a nation; see Ecc 10:16; and all this is usually for some national sin or sins indulged to, which draw upon a people the divine resentment, and provoke God to suffer such changes among there;

but by a man of understanding and knowledge the state thereof shall be prolonged, either by a set of wise and understanding, good and virtuous men, who will oppose the growing vice and immoralities of a people, and form themselves into societies for the reformation of manners; the word "man" being taken collectively for a body of men: or by a wise and prudent minister or ministry, or a set of civil magistrates, who will show themselves to be terrors to evildoers, and a praise to them that do well: or by a wise and prudent prince, who seeks to establish his throne by judgment and mercy; who will take care that justice and judgment be executed in the land, and that vice and profaneness be discouraged; by means of such, the state of a kingdom, which seemed near to ruin, will be prolonged, and the happiness and prosperity of it secured and established; and God, in mercy to it, may long preserve the life of their king, will being a good one, a long reign is always a happiness to a nation. And to this sense is the Vulgate Latin version, "the life of the prince shall be longer"; and the Targum, which is,

"and the sons of men that understand knowledge shall endure;''

see Ecc 9:15.

Anarchy producing contending rulers shortens the reign of each.

but by a man . . . prolonged--or, "by a man of understanding--that is, a good ruler--he who knows or regards the right, that is, a good citizen, shall prolong (his days)." Good rulers are a blessing to the people. Bad government as a punishment for evil is contrasted with good as blessing to the good.
