2 Kings 19:5-8

So the servants of king Hezekiah came to Isaiah. And Isaiah said unto them, Thus shall ye say to your master, Thus saith Jehovah, Be not afraid of the words that thou hast heard, wherewith the servants of the king of Assyria have blasphemed me. Behold, I will put a spirit in him, and he shall hear tidings, and shall return to his own land; and I will cause him to fall by the sword in his own land. So Rabshakeh returned, and found the king of Assyria warring against Libnah; for he had heard that he was departed from Lachish.
