2 Kings 18:17-20

17Then the king of Assyria sent the Tartan, the Rab-saris and the Rab-shakeh from Lachish with a great army to King Hezekiah in Jerusalem. So they went up and arrived at Jerusalem. Now when they arrived, they stood by the conduit of the upper pool, which is on the highway of the fuller’s field.

18When they had called to the king, Eliakim son of Hilkiah, who was in charge of the royal palace, Shebnah the scribe, and Joah son of Asaph the recorder, came out to them.

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?
