'Sword' in the Bible

For I have bent Judah for me, I have filled the bow with Ephraim; and I will stir up thy sons, O Zion, against thy sons, O Greece, and will make thee as 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 shall be utterly darkened.

Awake, O sword, against my shepherd, and 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.
