Proverbs 9:7-9

New International Version - UK

⁷ Whoever corrects a mocker invites insults;
    whoever rebukes the wicked incurs abuse.
⁸ Do not rebuke mockers or they will hate you;
    rebuke the wise and they will love you.
⁹ Instruct the wise and they will be wiser still;
    teach the righteous and they will add to their learning.
