Isaiah 37:10

Now in the fourteenth year of King Hezekiah, Sennacherib king of Assyria came up against all the fortified cities of Judah and seized them.

After these acts of faithfulness Sennacherib king of Assyria came and invaded Judah and encamped against the fortified cities, and thought to break into them for himself.

And the king of Assyria sent Rabshakeh from Lachish to Jerusalem to King Hezekiah with a heavy military force. And he stood by the conduit of the upper pool on the highway of the fuller’s field.

“Thus says the king, ‘Do not let Hezekiah deceive you, for he will not be able to deliver you;

and do not let Hezekiah make you trust in Yahweh, saying, “Yahweh will surely deliver us, this city will not be given into the hand of the king of Assyria.”

Now it happened that when King Hezekiah heard it, he tore his clothes, covered himself with sackcloth, and entered the house of Yahweh.
