2 Kings 19:5-8

So the servants of King Hezekiah came to Isaiah. Isaiah said to them, “Say this to your master: ‘Thus says the LORD, “Do not be afraid because of the words that you have heard, with which the servants of the king of Assyria have reviled (blasphemed) Me. Behold, I will put a spirit in him so that he will hear a rumor and return to his own land. And I will make him fall by the sword in his own land.” ’ ” So the Rabshakeh returned and found the king of Assyria fighting against Libnah [a fortified city of Judah]; for he had heard that the king had left Lachish.
