Isaiah 38:5-8

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

6and rescue you and this city from the king of Assyria. I will shield this city.”’”

7Isaiah replied, “This is your sign from the Lord confirming that the Lord will do what he has said:

8Look, I will make the shadow go back ten steps on the stairs of Ahaz.” And then the shadow went back ten steps.
