2 Kings 20:5-11

5“Go back and tell Hezekiah the leader of My people, ‘Thus says the Lord, the God of David your father (ancestor): “I have heard your prayer, I have seen your tears. Behold, I am healing you; on the third day you shall go up to the house of the Lord.

6I will add fifteen years to your life and save you and this city [Jerusalem] from the hand of the king of Assyria; and I will protect this city for My own sake and for My servant David’s sake.” ’ ”

7Then Isaiah said, “Bring a cake of figs. And they brought it and placed it on the [painful] inflammation, and he recovered.”

8Hezekiah said to Isaiah, “What will be the sign that the Lord will [completely] heal me, and that I shall go up to the house of the Lord on the third day?”

9Isaiah said, “This will be the sign to you from the Lord, that He will do the thing that He has spoken: shall the shadow [indicating the time of day] go forward ten steps, or go backward ten steps?”

10Hezekiah answered, “It is easy for the shadow to go forward ten steps; no, but let the shadow turn backward ten steps.”

11So Isaiah the prophet called out to the Lord, and He brought the shadow on the steps ten steps backward by which it had gone down on the sundial of Ahaz.
