Albert Barnes Commentary Proverbs 28:2

"For the transgression of a land many are the princes thereof; But by men of understanding [and] knowledge the state [thereof] shall be prolonged." — Proverbs 28:2 (ASV)

Transgression - Better, rebellion. A revolt against a ruler leads to rapid changes of dynasty (the whole history of the kingdom of Israel was a proof of this), but “with men of understanding and knowledge thus shall he (the prince) continue.” True wisdom will lead people to maintain an existing order. The King James Version implies that political disorders may come as the punishment of any national sin.

The state - Better, it (the land) shall surely prolong its days in stability.
