2 Kings 20:8-10

New American Standard Bible

⁸ Now Hezekiah said to Isaiah, “What will be the sign that the Lord will heal me, and that I will go up to the house of the Lord on the third day?” 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.”
