Isaiah 36:4; Isaiah 36:6

4 And the Rabshakeh said to them, "Say to Hezekiah, 'Thus says the great king, the king of Assyria: On what do you rest this trust of yours?

6 Behold, you are trusting in Egypt, that broken reed of a staff, which will pierce the hand of any man who leans on it. Such is Pharaoh king of Egypt to all who trust in him.
