4Then the word of the LORD came to Isaiah: 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.
