2 Kings 20:7-11

⁷Then Isaiah said, “Take a cake of figs.” And they took it and placed it on the inflamed spot, and he recovered.

⁸Now Hezekiah said to Isaiah, “What will be the sign that the Lord will heal me, and that I will go up to the house of the Lord on the third day?” ⁹Isaiah said, “This shall be the sign to you from the Lord, that the Lord will perform the word that He has spoken: shall the shadow go forward ten steps or go back ten steps?” ¹⁰So Hezekiah said, “It is easy for the shadow to decline ten steps; no, but have the shadow turn backward ten steps.” ¹¹Then Isaiah the prophet called out to the Lord, and He brought the shadow on the stairway back ten steps by which it had gone down on the stairway of Ahaz.
