Isaiah 38:5-8

5“Go and tell Hezekiah, ‘This is what the Lord, the God of your father David, says: I have heard your prayer and seen your tears; I will add fifteen years to your life.

6And I will deliver you and this city from the hand of the king of Assyria. I will defend this city.

7“ ‘This is the Lord’s sign to you that the Lord will do what he has promised:

8I will make the shadow cast by the sun go back the ten steps it has gone down on the stairway of Ahaz.’ ” So the sunlight went back the ten steps it had gone down.
