2 Kings 20:9-11

New Living Translation

⁹ Isaiah replied, “This is the sign from the Lord to prove that he will do as he promised. Would you like the shadow on the sundial to go forward ten steps or backward ten steps?^[a]”

¹⁰ “The shadow always moves forward,” Hezekiah replied, “so that would be easy. Make it go ten steps backward instead.” ¹¹ So Isaiah the prophet asked the Lord to do this, and he caused the shadow to move ten steps backward on the sundial^[b] of Ahaz!
