What the Bible says about Rising of the Sun
(From Forerunner Commentary)
The metaphor is drawn from the rising of the sun and being able to get to work and produce solutions. God pictures the whole earth covered by a thick cloud of darkness that dissolves in the light. The terms "arise," "shine," "glory of the LORD," and "brightness of your rising" give every indication of our resurrection to glory to meet the returning Christ. Because of the "rising" of Zion, mankind will be prospered in every way, morally, spiritually, intellectually, emotionally, and physically.
