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. On the third day from now you will go up to the Lord’s temple.

6I will add fifteen years to your life. I will rescue you and this city from the grasp of the king of Assyria. I will defend this city for my sake and for the sake of my servant David.’”
