John Gill's Exposition of the Whole Bible
Proverbs 29:2
When the righteous are in authority,.... Or "are increased" g; either in number or in riches, or in power and dominion; are set in high places, and have the exercise of civil government and the execution of the laws in their hands; for the protection of good men in their civil and religious privileges, and for the punishment of evil men; for the encouraging of all that is good, and for the discouraging of everything that is bad;
the people rejoice; the whole body of the people, because of the public good; a state is happy under such an administration; everyone feels and enjoys the advantage of it; see 1 Kings 4:20;
but when the wicked beareth rule, the people mourn; or "groan" h, or "will groan", under their tyranny and oppression, and because of the sad state of things; the number of good men is lessened, being cut off, or obliged to flee; wicked men and wickedness are encouraged and promoted; heavy taxes are laid upon them, and exorbitant demands made and cruelty, injustice, and arbitrary power exercised; and no man's person and property safe; see Proverbs 10:11.
