'Expanse Of The Sky' in the Bible

And God said, “Let there be an expanse [of the sky] in the midst of the waters, and let it separate the waters [below the expanse] from the waters [above the expanse].”

Then God said, “Let there be lights in the expanse of the sky to separate the day from the night. They will serve as signs for festivals and for days and years.

and let them be useful as lights in the expanse of the heavens to provide light on the earth”; and it was so, [just as He commanded].

God placed them in the expanse of the sky to provide light on the earth,

Then God said, “Let the water swarm with living creatures, and let birds fly above the earth across the expanse of the sky.”
