'Expanse' in the Bible

Then God said, “Let there be an expanse between the waters, separating water from water.”

So God made the expanse and separated the water under the expanse from the water above the expanse. And it was so.

God called the expanse “sky.” Evening came and then morning: the second day.

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.

They will be lights in the expanse of the sky to provide light on the earth.” And it was so.

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.”
