Proverbs 17:9

⁷ Eloquent words are unfit for a fool; how much worse are lying lips to a ruler!

⁸ A bribe is a charm to its giver; wherever he turns, he succeeds.

Whoever conceals an offense promotes love, but he who brings it up separates friends.

¹⁰ A rebuke cuts into a man of discernment deeper than a hundred lashes cut into a fool.

¹¹ An evil man seeks only rebellion; a cruel messenger will be sent against him.

Do read the surrounding verses too, because the context often says more than a single verse.
