2 Kings 20:5-6

“Go back and tell Hezekiah, the leader of my people: ‘This is what the LORD, the God of your ancestor David, says: I have heard your prayer and seen your tears, so I will heal you. Three days from now you will go up to the Temple of the LORD. I will add fifteen years to your life. I will save you and this city from the king of Assyria; I will protect the city for my sake and for the sake of my servant David.’ ”
