Psalms 55:20-23

My companion attacks his friends; he violates his covenant. His talk is smooth as butter, yet war is in his heart; his words are more soothing than oil, yet they are drawn swords. Cast your cares on the LORD and he will sustain you; he will never let the righteous be shaken. But you, God, will bring down the wicked into the pit of decay; the bloodthirsty and deceitful will not live out half their days.
