Psalms 55:21

The words of his mouth were smoother than butter ,.... Such were the words of Ahithophel, when in counsel with David; and such the words of Judas, when he said to Christ, "hail, master", and kissed him, Matthew 26:49 ;

but war was in his heart ; even a civil war, rebellion against his prince; that was what Ahithophel meditated in his heart; and nothing less than to take away the life of Christ was designed by Judas. The words may be rendered, "they were divided" F5 חלקו διεμερισθησαν , Sept. "divisi sunt", V. L. Hammond. ; that is, his mouth and his heart: "his mouth was butter, and his heart war"; the one declared for peace, when the other intended war; see Jeremiah 9:8 ;

his words were softer than oil ; at one time full of soothing and flattery:

yet were they drawn swords : at another time sharp and cutting, breathing out threatening and slaughter, destruction and death.
