Isaiah 36:4-6

And Rabshakeh said unto them, Say ye now to Hezekiah, Thus saith the great king, the king of Assyria, What confidence is this wherein thou trustest? I say, thy counsel and strength for the war are but vain words: now on whom dost thou trust, that thou hast rebelled against me? Behold, thou trustest upon the staff of this bruised reed, even upon Egypt, whereon if a man lean, it will go into his hand, and pierce it: so is Pharaoh king of Egypt to all that trust on him.
