2 Kings 20:4-6

Isaiah, leaving, was not halfway across the courtyard when the word of GOD stopped him: “Go back and tell Hezekiah, prince of my people, ‘GOD’s word, Hezekiah! From the God of your ancestor David: I’ve listened to your prayer and I’ve observed your tears. I’m going to heal you. In three days you will walk on your own legs into The Temple of GOD. I’ve just added fifteen years to your life; I’m saving you from the king of Assyria, and I’m covering this city with my shield—for my sake and my servant David’s sake.’”
