Psalms 55:21-23

²¹The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.

²²Cast thy burden upon the LORD, and he shall sustain thee: he shall never suffer the righteous to be moved.

²³But thou, O God, shalt bring them down into the pit of destruction: bloody and deceitful men shall not live out half their days; but I will trust in thee.
