II Kings 19:5-7

So the servants of King Hezekiah came to Isaiah. And Isaiah said to them, “Thus you shall say to your master, ‘Thus says the LORD: “Do not be afraid of the words which you have heard, with which the servants of the king of Assyria have blasphemed Me. Surely I will send a spirit upon him, and he shall hear a rumor and return to his own land; and I will cause him to fall by the sword in his own land.” ’ ”
