2 Kings 18:17-21

17Then the king of Assyria sent the Tartan, the Rabsaris, and the Rabshakeh from Lachish, with a great army against Jerusalem, to King Hezekiah. And they went up and came to Jerusalem. When they had come up, they went and stood by the aqueduct from the upper pool, which was on the highway to the Fuller’s Field.

18And when they had called to the king, Eliakim the son of Hilkiah, who was over the household, Shebna the scribe, and Joah the son of Asaph, the recorder, came out to them.

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.
