Proverbs 18:5-8

⁵To have respect for the person of the evil-doer is not good, or to give a wrong decision against the upright.

⁶A foolish man's lips are a cause of fighting, and his mouth makes him open to blows.

⁷The mouth of a foolish man is his destruction, and his lips are a net for his soul.

⁸The words of one who says evil of his neighbour secretly are like sweet food, and go down into the inner parts of the stomach.
