2 Kings 9:13; 2 Kings 20:9-11
Then they hasted , and took every man his garment, and put it under him on the top of the stairs, and blew with trumpets, saying , Jehu is king .
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?
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.
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.
