Proverbs 14:7-9

Authorized (King James) Version

⁷ Go from the presence of a foolish man,
    when thou perceivest not in him the lips of knowledge.

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.
