'Sword' in the Bible

For I have bent Judah for me, I have filled the bow with Ephraim; and I will raise up thy sons, O Zion, against thy sons, O Greece, and make thee like the sword of a mighty man.

Woe to the worthless shepherd that leaveth the flock! The sword shall be upon his arm, and upon his right eye; his arm shall be clean dried up, and his right eye utterly darkened.

Awake, O sword, against my shepherd, even against the man that is my fellow, saith Jehovah of hosts: smite the shepherd, and the sheep shall be scattered, and I will turn my hand upon the little ones.
