'Staff' in the Bible

Thus saith Jehovah of hosts: There shall yet old men and old women sit in the streets of Jerusalem, each one with his staff in his hand for multitude of days.

And I took my staff, Beauty, and cut it asunder, that I might break my covenant which I had made with all the peoples.

And I cut asunder mine other staff, Bands, to break the brotherhood between Judah and Israel.
