2 Kings 20:5-6

“Return; you must say to Hezekiah, the leader of my people, ‘Thus says Yahweh the God of David your ancestor, “I have heard your prayer and I have seen your tears. Look, I am about to heal you. On the third day you shall go up to the temple of Yahweh. I will add to your days fifteen years, and from the hand of the king of Assyria I will deliver you and this city. I will defend this city for my sake and for the sake of David my servant.” ’ ”
