"Therefore thus says the LORD concerning the king of Assyria: He shall not come into this city, or shoot an arrow there, or come before it with a shield, or cast up a siege mound against it. By the way that he came, by the same he shall return, and he shall not come into this city, says the LORD. For I will defend this city to save it, for my own sake and for the sake of my servant David." And the angel of the LORD went forth, and slew a hundred and eighty-five thousand in the camp of the Assyrians; and when men arose early in the morning, behold, these were all dead bodies. Then Sennacherib king of Assyria departed, and went home and dwelt at Nineveh. And as he was worshiping in the house of Nisroch his god, Adrammelech and Sharezer, his sons, slew him with the sword, and escaped into the land of Ararat. And Esarhaddon his son reigned in his stead.

In those days Hezekiah became sick and was at the point of death. And Isaiah the prophet the son of Amoz came to him, and said to him, "Thus says the LORD: Set your house in order; for you shall die, you shall not recover." Then Hezekiah turned his face to the wall, and prayed to the LORD, and said, "Remember now, O LORD, I beseech thee, how I have walked before thee in faithfulness and with a whole heart, and have done what is good in thy sight." And Hezekiah wept bitterly. Then the word of the LORD came to Isaiah: "Go and say to Hezekiah, Thus says the LORD, the God of David your father: I have heard your prayer, I have seen your tears; behold, I will add fifteen years to your life. I will deliver you and this city out of the hand of the king of Assyria, and defend this city.
