'Expanse' in the Bible

God said, "Let there be an expanse in the midst of the waters and let it separate water from water.

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

God called the expanse "sky." There was evening, and there was morning, a second day.

God said, "Let there be lights in the expanse of the sky to separate the day from the night, and let them be signs to indicate seasons and days and years,

and let them serve as lights in the expanse of the sky to give light on the earth." It was so.

God placed the lights in the expanse of the sky to shine on the earth,

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