Proverbs 9:11

⁹ Instruct a wise man, and he will be wiser still; teach a righteous man, and he will increase his learning.

¹⁰ The fear of the LORD is the beginning of wisdom, and knowledge of the Holy One is understanding.

For through wisdom your days will be multiplied, and years will be added to your life.

¹² If you are wise, you are wise to your own advantage; but if you scoff, you alone will bear the consequences.

¹³ The woman named Folly is loud; she is naive and knows nothing.

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