2 Kings 20:9-11

New American Standard Bible

⁹ Isaiah said, “^(A)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?” ¹⁰ So Hezekiah said, “It is easy for the shadow to decline ten steps; no, but have the shadow turn backward ten steps.” ¹¹ Then Isaiah the prophet called out to the Lord, and ^(B)He brought the shadow on the ^[a]stairway back ten steps by which it had gone down on the ^[b]stairway of Ahaz.
