Psalms 55:20-23

20My companion attacks his friends; he violates his covenant.

21His talk is smooth as butter, yet war is in his heart; his words are more soothing than oil, yet they are drawn swords.

22Cast your cares on the Lord and he will sustain you; he will never let the righteous be shaken.

23But you, God, will bring down the wicked into the pit of decay; the bloodthirsty and deceitful will not live out half their days. But as for me, I trust in you.
