Psalm 50:19-21

Revised Standard Version Catholic Edition

¹⁹ “You give your mouth free rein for evil,
    and your tongue frames deceit.
²⁰ You sit and speak against your brother;
    you slander your own mother’s son.
²¹ These things you have done and I have been silent;
    you thought that I was one like yourself.
But now I rebuke you, and lay the charge before you.
