Bede

But her end is bitter, etc. The drink of wormwood becomes bitter within the bowels, outwardly the members are wounded by the sword. Therefore, to show the wicked in the final retribution, both internally to be filled, and externally surrounded by perpetual punishments, he assures that they will be tormented by the bitterness of wormwood, and slaughtered by the sword. And why the same sword is called two-edged, the Lord opens when he says: But fear him who can destroy both soul and body in hell (Matthew 10).
