Isaiah 36:1-2

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