2 Kings 20:5-6

“Return and say to Hezekiah the leader of My people, ‘Thus says the LORD, the God of your father David, “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. I will add fifteen years to your life, and I will deliver you and this city from the hand of the king of Assyria; and I will defend this city for My own sake and for My servant David’s sake.” ’ ”
