Proverbs 28:16 - Joseph Benson’s Commentary on the Old and New Testaments

The prince that wanteth understanding, &c. The tyranny or oppression of a prince is a manifest sign of great folly, because it alienates from him the hearts of his people, in possessing which his honour, safety, and riches consist; and often causes the shortening of his days, either through God's cutting him off by some sudden stroke, or through the violence of men who have been injured by him, and are exasperated against him. But he that hateth covetousness Which is the chief cause of all oppression and unjust practices; shall prolong his days By God's favour, the peace and satisfaction of his own mind, and the hearty love of his people, which induces them to pray fervently to God to preserve his life, and makes them willing to hazard their estates and lives in his defence.
