2 Kings 18:19-21

19The Rabshakeh said to them, “Tell Hezekiah that this is what the great king, the king of Assyria, says: What is the basis of this confidence of yours? 20You claim to have a strategy and strength for war, but these are empty words. In whom are you now trusting, that you have rebelled against me?

21Look now, you are trusting in Egypt, that splintered reed of a staff that will pierce the hand of anyone who leans on it. Such is Pharaoh king of Egypt to all who trust in him.
