Psalms 55:20-23

He [my companion] has put out his hands against those who were at peace with him; He has broken his covenant [of friendship and loyalty]. The words of his mouth were smoother than butter, But his heart was hostile; His words were softer than oil, Yet they were drawn swords. ¶Cast your burden on the LORD [release it] and He will sustain and uphold you; He will never allow the righteous to be shaken (slip, fall, fail). [1 Pet 5:7] But You, O God, will bring down the wicked to the pit of destruction; Men of blood and treachery will not live out half their days. But I will [boldly and unwaveringly] trust in You.
