His talk is smooth as butter, yet war is in his heart; his words are more soothing than oil, yet they are drawn swords. (NIV)
The words of his mouth were smoother than cream or butter, but war was in his heart; his words were softer than oil, yet they were drawn swords. (AMP)
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. (KJV)
