'Staff' in the Bible

And He saith unto me, 'Son of man, lo, I am breaking the staff of bread in Jerusalem, and they have eaten bread by weight and with fear; and water by measure and with astonishment, they do drink;

In My sending the evil arrows of famine among them, That have been for destruction, That I send to destroy you, And famine I am adding upon you, And I have broken to you the staff of bread.

Son of man, the land -- when it sinneth against Me to commit a trespass, and I have stretched out My hand against it, and broken for it the staff of bread, and sent into it famine, and cut off from it man and beast --

And known have all inhabitants of Egypt That I am Jehovah, Because of their being a staff of reed to the house of Israel.
