Psalms 55:21-23

MLV(i) 21 His mouth was smooth as butter, but his heart was war. His words were softer than oil, yet they were drawn swords. 22 (Cast your burden upon Jehovah and he will sustain you. He will not allow the righteous man to be shaken everlasting.)
23 But you, O God, will bring them down into the pit of destruction. Bloodthirsty and deceitful men will not live out half their days, but I will trust in you.
