2 Kings 20:8-11 King James Version (KJV)
8 And Hezekiah said unto Isaiah, What shall be the sign that the Lord will heal me, and that I shall go up into the house of the Lord the third day?
9 And Isaiah said, This sign shalt thou have of the Lord, that the Lord will do the thing that he hath spoken: shall the shadow go forward ten degrees, or go back ten degrees?
10 And Hezekiah answered, It is a light thing for the shadow to go down ten degrees: nay, but let the shadow return backward ten degrees.
11 And Isaiah the prophet cried unto the Lord: and he brought the shadow ten degrees backward, by which it had gone down in the dial of Ahaz.
2 Kings 20:8-11 New International Version (NIV)
8 Hezekiah had asked Isaiah, “What will be the sign that the Lord will heal me and that I will go up to the temple of the Lord on the third day from now?”
9 Isaiah answered, “This is the Lord’s sign to you that the Lord will do what he has promised: Shall the shadow go forward ten steps, or shall it go back ten steps?”
10 “It is a simple matter for the shadow to go forward ten steps,” said Hezekiah. “Rather, have it go back ten steps.”
11 Then the prophet Isaiah called on the Lord, and the Lord made the shadow go back the ten steps it had gone down on the stairway of Ahaz.
