He hath put forth his hands against such as be at peace with him: he hath broken his covenant. The 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.
Cast thy burden upon the LORD, and He shall sustain thee: He shall never suffer the righteous to be moved.  But 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.

Psalm 55:20-23

Be sure to read all twenty three verses of Psalm 55, and see First Peter 5:7 as well.
