Proverbs 9:8-10

Revised Standard Version Catholic Edition

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.
¹⁰ The fear of the Lord is the beginning of wisdom,
    and the knowledge of the Holy One is insight.
