2 Kings 18:19-21

19So the Rab-shakeh said to them, “Say now to Hezekiah, thus says the great king, the king of Assyria: ‘What is this confidence you’ve relied on?

20You say you have a plan and military force for the battle—they are only words of a lip. Who do you rely on now, so that you have rebelled against me?

21Behold, you rely on this splintered reed as a staff—Egypt! If a man leans on it, it will go into the palm of his hand and pierce it—thus Pharaoh king of Egypt is to all who trust in him.
