Isaiah 38:5-8

5‘Go and say this to Hezekiah: “This is what the Lord says, the God that your ancestor David worshipped. I have heard your prayer and I have seen your tears. So I will let you live for 15 more years.

6I will rescue you and this city from the power of the king of Assyria. I will keep Jerusalem safe.” ’

7Isaiah said, ‘The Lord will do what he has promised to do for you. This is how you will know that it will really happen.

8You can see the sun's shadow when it falls on the stairs that King Ahaz built. The Lord will cause the shadow to go back ten steps on these stairs.’ Then the shadow did go back ten steps!
