2 Kings 20:5-6

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.

6I 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.”’”
