'Sword' in the Bible

For I will bend Judah as My bow,I will fill the bow with Ephraim.And I will stir up your sons, O Zion, against your sons, O Greece;And I will make you like a warrior’s sword.

“Woe to the worthless shepherdWho leaves the flock!A sword will be on his armAnd on his right eye!His arm will be totally witheredAnd his right eye will be blind.”

“Awake, O sword, against My Shepherd,And against the man, My Associate,”Declares the Lord of hosts.“Strike the Shepherd that the sheep may be scattered;And I will turn My hand against the little ones.
