2 Kings 20:2-6

When Hezekiah heard this, he turned his face to the wall and prayed to the LORD, “Remember, O LORD, how I have always been faithful to you and have served you single-mindedly, always doing what pleases you.” Then he broke down and wept bitterly. But before Isaiah had left the middle courtyard, this message came to him from the LORD: “Go back to Hezekiah, the leader of my people. Tell him, ‘This is what the LORD, the God of your ancestor David, says: I have heard your prayer and seen your tears. I will heal you, and three days from now you will get out of bed and go to the Temple of the LORD. I will add fifteen years to your life, and I will rescue you and this city from the king of Assyria. I will defend this city for my own honor and for the sake of my servant David.’”
