'Staff' in the Bible

Then he said to Gehazi, "Tuck your cloak into your belt, take my staff in your hand, and go your way. If you meet any man, don't greet him; and if anyone greets you, don't answer him again. Then lay my staff on the face of the child."

Gehazi passed on before them, and laid the staff on the face of the child; but there was neither voice, nor hearing. Therefore he returned to meet him, and told him, saying, "The child has not awakened."

Now, behold, you trust in the staff of this bruised reed, even in Egypt. If a man leans on it, it will go into his hand, and pierce it. So is Pharaoh king of Egypt to all who trust on him.
