Proverbs 9:7-9

Revised Standard Version

⁷ He who corrects a scoffer gets himself abuse,
    and he who reproves a wicked man incurs injury.
⁸ Do not reprove a scoffer, or he will hate you;
    reprove a wise man, and he will love you.
⁹ Give instruction^[a] to a wise man, and he will be still wiser;
    teach a righteous man and he will increase in learning.
