Proverbs 14:8-10

Authorized (King James) Version

⁸ The wisdom of the prudent is to understand his way:
    but the folly of fools is deceit.

⁹ Fools make a mock at sin:
    but among the righteous there is favour.

¹⁰ The heart knoweth his own bitterness;
    and a stranger doth not intermeddle with his joy.
