2 Kings 19:4-8

It may be that the LORD your God heard all the words of the Rabshakeh, whom his master the king of Assyria has sent to mock the living God, and will rebuke the words that the LORD your God has heard; therefore lift up your prayer for the remnant that is left.” When the servants of King Hezekiah came to Isaiah, Isaiah said to them, “Say 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 me. Behold, I will put a spirit in him, so that he shall hear a rumor and return to his own land, and I will make him fall by the sword in his own land.’” LORD The Rabshakeh returned, and found the king of Assyria fighting against Libnah, for he heard that the king had left Lachish.
