"Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it was gone down.” (Isaiah 38:8)
I completely forgot about that passage. However it was only God playing astronomy tricks to make a particular point; I don't recall any case where there is written that the Earth is supposed to start rotating backwards in the future (or the Sun going in the other direction, etc.)
