2 Kings 18:19-21

19Then the Rabshakeh said to them, “Say now to Hezekiah, ‘Thus says the great king, the king of Assyria: “What confidence is this in which you trust?

20You speak of having plans and power for war; but they are mere words. And in whom do you trust, that you rebel against me?

21Now look! You are trusting in the staff of this broken reed, Egypt, on which if a man leans, it will go into his hand and pierce it. So is Pharaoh king of Egypt to all who trust in him.
