'Edge of the Sword' in the Bible

And after that, Declareth Yahweh - Will I deliver Zedekiah king of Judah and his servants, and the people - even such as are left in this city from the pestilence from the sword and from the famine, - into the hand of Nebuchadrezzar king of Babylon, even into the hand of their enemies, and into the hand of them who are seeking their life, - and he will smite them with the edge of the sword, he will not have pity on them nor will he spare nor will he have compassion.
