'Staff' in the Bible

Look! The day is coming; doom goes out, the staff blossoms, pride sprouts.

Violence has grown to [become] a staff of wickedness; {none} from them [will remain], and {none} from their abundance nor from their wealth; and prominence [will] not [be] among them.

And all of the inhabitants of Egypt will know that I [am] Yahweh, because of their being a staff of reed for the house of Israel.
