Psalms 50:19-21

¹⁹You give your mouth to evil, and your tongue expresses deceit.

²⁰You sit and speak against your brother; you slander your own mother's son.

²¹You have done these things, but I have kept silent, so you thought that I was someone just like yourself. But I will reprove you and bring up, right before your eyes, all the things you have done.
