'Degrees' in the Bible

And Isaiah said, This shall be the sign to thee from Jehovah, that Jehovah will do the thing that he hath spoken: shall the shadow go forward ten degrees, or go back ten degrees?

And Hezekiah said, It is a light thing for the shadow to go down ten degrees: no, but let the shadow return backward ten degrees.

And Isaiah the prophet cried to Jehovah, and he brought the shadow back on the degrees by which it had gone down on the dial of Ahaz, ten degrees backward.
