'Staff' in the Bible

But Jonathan had not heard when his father adjured the people; and he put forth the end of his staff which was in his hand, and dipped it in the honeycomb, and put his hand to his mouth, and his eyes became bright.

And Saul said to Jonathan, Tell me what thou hast done. And Jonathan told him and said, With the end of the staff which is in my hand I tasted a little honey, and behold, I must die!

And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in the shepherd's bag that he had, into the pocket; and his sling was in his hand. And he drew near to the Philistine.
