“The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalm 19:1 KJV).
Deuteronomy 10:14 KJV, makes known of the heavenly spheres beyond, that are visible from the earth. “Indeed heaven and the highest heavens belong to the Lord your God, also the earth with all that is in it.”
The three heavens are: Our immediate atmosphere, Outer space (the sun, moon, and stars) and The home of God.
