Psalm 50:19-21

Complete Jewish Bible

¹⁹ you give your mouth free rein for evil
and harness your tongue to deceit;
²⁰ you sit and speak against your kinsman,
you slander your own mother’s son.
²¹ When you do such things, should I stay silent?
You may have thought I was just like you;
but I will rebuke and indict you to your face.
