'Staff' in the Bible

For You have shattered their oppressive yokeand the rod on their shoulders,the staff of their oppressor,just as You did on the day of Midian.

Woe to Assyria, the rod of My anger—the staff in their hands is My wrath.

Does an ax exalt itselfabove the one who chops with it?Does a saw magnify itselfabove the one who saws with it?It would be like a staff waving the one who lifts it!It would be like a rod lifting a man who isn’t wood!

Therefore, the Lord God of Hosts says this: “My people who dwell in Zion, do not fear Assyria, though he strikes you with a rod and raises his staff over you as the Egyptians did.

And the Lord of Hosts will brandish a whip against him as He did when He struck Midian at the rock of Oreb; and He will raise His staff over the sea as He did in Egypt.

The Lord has broken the staff of the wicked,the scepter of the rulers.

And every stroke of the appointed staffthat the Lord brings down on himwill be to the sound of tambourines and lyres;He will fight against him with brandished weapons.

Look, you are trusting in Egypt, that splintered reed of a staff that will enter and pierce the hand of anyone who leans on it. This is how Pharaoh king of Egypt is to all who trust in him.
