2 Kings 20:8

“Turn back, and tell Hezekiah the prince of my people, ‘The LORD, the God of David your father, says, “I have heard your prayer. I have seen your tears. Behold, I will heal you. On the third day, you will go up to the LORD’s house.

I will add to your days fifteen years. I will deliver you and this city out of the hand of the king of Assyria. I will defend this city for my own sake, and for my servant David’s sake.”’”

Isaiah said, “Take a cake of figs.”

They took and laid it on the boil, and he recovered.

Isaiah said, “This will be the sign to you from the LORD, that the LORD will do the thing that he has spoken: should the shadow go forward ten steps, or go back ten steps?”

Hezekiah answered, “It is a light thing for the shadow to go forward ten steps. No, but let the shadow return backward ten steps.”

Isaiah the prophet cried to the LORD; and he brought the shadow ten steps backward, by which it had gone down on the sundial of Ahaz.
