'Staff' in the Bible

“From Ephraim those whose root is in Amalek came down,Following you, Benjamin, with your peoples;From Machir commanders came down,And from Zebulun those who wield the staff of office.

Then the angel of the Lord put out the end of the staff that was in his hand and touched the meat and the unleavened bread; and fire sprang up from the rock and consumed the meat and the unleavened bread. Then the angel of the Lord vanished from his sight.
