11 And he hath given it to be furbished, that it may be handled: this sword is sharpened, and it is furbished, to give it into the hand of the slayer.
12 Cry and howl, son of man: for it shall be upon my people, it shall be upon all the princes of Israel: terrors by reason of the sword shall be upon my people: smite therefore upon thy thigh.
