David said to all his servants who were with him at Jerusalem, “Arise and let us flee; for otherwise none of us will escape from Absalom. Make speed to depart, lest he overtake us quickly and bring down evil on us, and strike the city with the mouth of the sword.” Bible

“the mouth of the sword.” Used to show great destruction, as if the sword was eating its victims (see commentary on Josh. 6:21).
