Psalm 55:20-23

My companion stretched out his hand against his friends; he violated his covenant. His speech was smooth as butter, yet war was in his heart; his words were softer than oil, yet they were drawn swords. Cast your burden on the LORD, and he will sustain you; he will never permit the righteous to be moved. But you, O God, will cast them down into the pit of destruction; men of blood and treachery shall not live out half their days. But I will trust in you.
