Proverbs 10:18-20

New Catholic Bible

¹⁸ Lying lips conceal hatred,
    and anyone who slanders another is a fool.
¹⁹ Where many words are spoken, sin is not absent,
    but whoever restrains his tongue is prudent.
²⁰ The tongue of the just man is like pure silver;
    the heart of the wicked is without worth.
