'Staff' in the Bible

For the yoke of his burden, and the staff of his shoulder, the rod of his oppressor, you have broken as in the day of Midian.

Alas Assyrian, the rod of my anger, the staff in whose hand is my indignation!

Should an axe brag against him who chops with it? Should a saw exalt itself above him who saws with it? As if a rod should lift those who lift it up, or as if a staff should lift up someone who is not wood.

Therefore the Lord, Yahweh of Armies, says "My people who dwell in Zion, don't be afraid of the Assyrian, though he strike you with the rod, and lift up his staff against you, as Egypt did.

Yahweh has broken the staff of the wicked, the scepter of the rulers,

Behold, you trust in the staff of this bruised reed, even in Egypt, which if a man leans on it, it will go into his hand and pierce it. So is Pharaoh king of Egypt to all who trust in him.
