'Battle ax' in the Bible

“You [Cyrus of Persia, soon to conquer Babylon] are My battle-axe and weapon of war—For with you I shatter nations,With you I destroy kingdoms.

Behold, six men [angelic beings] came from the direction of the Upper Gate, which faces north, each with his battle-axe in his hand; and among them was a certain man clothed in linen, with a scribe’s writing case at his side. They entered and stood beside the bronze altar.
