Proverbs 17:9-11

New Catholic Bible

⁹ One who forgives a misdeed fosters friendship,
    but he who divulges it separates good friends.
¹⁰ A reproof makes a far greater impression upon a discerning person
    than a hundred blows will upon a fool.
¹¹ A wicked man is only interested in fomenting rebellion;
    hence a cruel messenger will be sent against him.
