8. And Hezekiah had 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 has spoken: shall the shadow go forward ten degrees or go back ten degrees?
10. And Hezekiah answered, It is an easy thing for the shadow to go down ten degrees, but not for the shadow to return backward ten degrees.
11. Then Isaiah, the prophet, cried unto the Lord, and he caused the shadow to return by the degrees by which it had gone down in the dial of Ahaz, ten degrees backward.
