Proverbs 10:18-20

New Revised Standard Version Catholic Edition

¹⁸ Lying lips conceal hatred,
    and whoever utters slander is a fool.
¹⁹ When words are many, transgression is not lacking,
    but the prudent are restrained in speech.
²⁰ The tongue of the righteous is choice silver;
    the mind of the wicked is of little worth.
