Isaiah 38:5-8 NIV

[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. [6] And 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: [8] I 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.
