Psalms 55:21-23

ISV(i) 21 His mouth is as smooth as butter, while war is in his heart. His words were as smooth as olive oil, while his sword is drawn. 22 Cast on the LORD whatever he sends your way, and he will sustain you. He will never allow the righteous to be shaken. 23 But you, God, bring them down to the Pit of corruption; bloodthirsty and deceitful people will not live out half their days. But I put my full confidence in you.
