Isaiah 36:1-2

Now it came to pass in the fourteenth year of king Hezekiah, that Sennacherib king of Assyria came up against all the fortified cities of Judah, and took them. And the king of Assyria sent Rabshakeh from Lachish to Jerusalem unto king Hezekiah with a great army. And he stood by the conduit of the upper pool in the highway of the fuller’s field.
