'Staff' in the Bible

Then he said to Gehazi, Gird up thy loins, and take my staff in thine hand, and go thy way: if thou meet any man, salute him not; and if any salute thee, answer him not again: and lay my staff upon the face of the child.

And Gehazi passed on before them, and laid the staff upon the face of the child; but there was neither voice, nor hearing. Wherefore he went again to meet him, and told him, saying, The child is not awaked.

Now, behold, thou trustest upon the staff of this bruised reed, even upon Egypt, on which if a man lean, it will go into his hand, and pierce it: so is Pharaoh king of Egypt unto all that trust on him.

Later on, Amon's staff conspired against him and killed the king inside his own home.
