2 Kings 18:19-21

19And Rabshakeh said to them, Speak ye now to Hezekiah, Thus saith the great king, the king of Assyria, What confidence is this in which thou trustest? 20Thou sayest, (but they are but vain words,) I have counsel and strength for the war. Now in whom dost thou trust, that thou rebellest against me?123 21Now, behold, thou trustest upon the staff of this bruised reed, even upon Egypt, on which if a man leaneth, it will go into his hand, and pierce it: so is Pharaoh king of Egypt to all that trust on him.4
