'Staffs' in the Bible

For each one threw down his staff and they turned into serpents. But Aaron’s staff swallowed up their staffs.

“The well, which the leaders sank,Which the nobles of the people dug,With the scepter and with their staffs.”And from the wilderness they continued to Mattanah,

So I pastured the flock doomed to slaughter, hence the afflicted of the flock. And I took for myself two staffs: the one I called Favor and the other I called Union; so I pastured the flock.
