Isaiah 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?”

So Hezekiah said, “It is easy for the shadow to decline ten steps; no, but have the shadow turn backward ten steps.”

Then 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.
