'Expanse' in the Bible

Then God said, “Let there be an expanse in the midst of the waters, and let it separate the waters from the waters.”

God made the expanse, and separated the waters which were below the expanse from the waters which were above the expanse; and it was so.

God called the expanse heaven. And there was evening and there was morning, a second day.

Then God said, “Let there be lights in the expanse of the heavens to separate the day from the night, and let them be for signs and for seasons and for days and years;

and let them be for lights in the expanse of the heavens to give light on the earth”; and it was so.

God placed them in the expanse of the heavens to give light on the earth,

Then God said, “Let the waters teem with swarms of living creatures, and let birds fly above the earth in the open expanse of the heavens.”
