2 Kings 20:5-6
20:5 “Go back and tell Hezekiah, the leader of my people: ‘This is what the Lord God of your ancestor David says: “I have heard your prayer; I have seen your tears. Look, I will heal you. The day after tomorrow you will go up to the Lord’s temple.
20:6 I will add fifteen years to your life and rescue you and this city from the king of Assyria. I will shield this city for the sake of my reputation and because of my promise to David my servant.”’”
