2 Kings 20:5-6

“Turn back, and say to Hezekiah the leader of my people, Thus says the LORD, the God of David your father: I have heard your prayer; I have seen your tears. Behold, I will heal you. On the third day you shall go up to the house of the LORD, and I will add fifteen years to your life. I will deliver you and this city out of the hand of the king of Assyria, and I will defend this city for my own sake and for my servant David’s sake.”
