Psalms 55:12, 20-21

¶For it is not an enemy who taunts me— Then I could bear it; Nor is it one who has hated me who insolently exalts himself against me— Then I could hide from him.

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.
