On hearing the Rabshakeh, Hezekiah tears his clothes, covers himself with sackcloth and enters the house of the Lord. He sends Eliakim, Shebna and the senior priests to Isaiah with a message: it is a day of distress and disgrace; perhaps the Lord will hear the words of the Rabshakeh, so lift up a prayer for the remnant. Isaiah answers that they should not fear: the Lord will put a spirit in the king of Assyria, he will hear a rumor, return to his land and fall there by the sword.
Sennacherib, already fighting against Libnah, hears that Tirhakah king of Cush has set out to fight him, and sends Hezekiah a letter: do not let your God deceive you, for the gods of other nations did not deliver them. Hezekiah takes the letter, goes up to the house of the Lord and spreads it out before him. He prays to the Lord of hosts, enthroned above the cherubim, the only God of all the kingdoms, maker of heaven and earth. He admits that the gods of the nations were wood and stone, and asks for salvation so that all may know that the Lord alone is God.
Isaiah sends the answer: the Lord has heard the prayer. The king of Assyria has mocked the Holy One of Israel; the Lord will put his hook in his nose and his bit in his mouth and turn him back the way he came. The remnant of Judah will take root downward and bear fruit upward. The king of Assyria will not enter the city or shoot an arrow there, for the Lord will defend it for his own sake and for David his servant.
Then the angel of the Lord strikes down 185,000 in the Assyrian camp; at dawn they are all dead bodies. Sennacherib returns to Nineveh, and while he is worshiping in the house of his god Nisroch, his sons Adrammelech and Sharezer strike him down with the sword and escape to Ararat. His son Esarhaddon reigns in his place.
