Ezekiel 21:9 - Matthew Poole's English Annotations on the Holy Bible

As if he pointed to it, crying out as one that suddenly seeth some dreadful sight. A mighty sword, or many; so the ingemination may imply the forces of Nebuchadnezzar and his confederates. Sharpened; prepared to wound, slay, and that with greater speed and sureness. Furbished; to terrify the weaker courage, to dazzle the eyes of such as encounter it: in a word, the danger is as near as if an army come up in array, and their swords in their bends ready to go on and fight.
