'Ax' in the Bible

Is the axe able to lift itself over the one who chops with it?Is the saw able to magnify itself over the one who wields it?That would be like a club moving those who lift it,Or like a staff raising him who is not [made of] wood [like itself]!

He will cut down the thickets of the forest with an iron axe,And Lebanon (the Assyrian) will fall by the Mighty One.
