    and the liar listens to malicious talk.

⁷ Appropriate speech is inconsistent with the fool;
    how much more are deceitful statements^[a] with a prince!

²⁰ The person whose mind^[a] is perverse does not find good,
    and anyone with perverted speech falls into trouble.

²⁷ Whoever controls what he says is knowledgeable;
    anyone who has a calm spirit is a man of understanding.

    he is thought to be prudent when he keeps his mouth shut.
