Psalms 50:18-21

¹⁸When you see a thief, you agree with him; you participate with those who commit adultery.

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.
