Thematic Bible: Shadow on ahaz' sun-dial

Hezekiah had asked Isaiah, "What is the sign that the Lord will heal me and that I will go up to the Lord's temple on the third day?" Isaiah said, "This is the sign to you from the Lord that He will do what He has promised: Should the shadow go ahead 10 steps or go back 10 steps?" Then Hezekiah answered, "It's easy for the shadow to lengthen 10 steps. No, let the shadow go back 10 steps." read more.
So Isaiah the prophet called out to the Lord, and He brought the shadow back the 10 steps it had descended on Ahaz's stairway.

This is the sign to you from the Lord that the Lord will do what He has promised: I am going to make the sun's shadow that goes down on Ahaz's stairway return by 10 steps." So the sun's shadow went back the 10 steps it had descended.
