⁴ An evildoer listens to wicked lips;
    and a liar gives heed to a mischievous tongue.

⁷ Fine speech is not becoming to a fool;
    still less is false speech to a prince.

²⁰ A man of crooked mind does not prosper,
    and one with a perverse tongue falls into calamity.

²⁷ He who restrains his words has knowledge,
    and he who has a cool spirit is a man of understanding.
²⁸ Even a fool who keeps silent is considered wise;
    when he closes his lips, he is deemed intelligent.
