'Expanse' in the Bible

God said, "Let there be an expanse in the middle of the waters, and let it divide the waters from the waters."

God made the expanse, and divided the waters which were under the expanse from the waters which were above the expanse; and 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 sky to divide 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 sky to give light on the earth;" and it was so.

God set them in the expanse of sky to give light to the earth,

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