2 Kings 20:8-10

International Standard Version

⁸ Now Hezekiah had asked Isaiah, “What is to be the sign that the Lord is healing me and that I’ll be going up to the Lord’s Temple three days from now?”

⁹ So Isaiah replied, “This will be your sign from the Lord that the Lord will do what he has promised. Shall the shadow go forward ten steps or go back ten steps?”

¹⁰ Hezekiah answered, “It’s an easy thing for a shadow to lengthen ten steps. So let the shadow go backward ten steps.”
