Thematic Bible: Second day, making the firmament or atmosphere, and separating the waters

And God said, "Let there be a firmament between the waters, and let it divide the waters asunder." Then God made the firmament, and parted the waters which were under the firmament, from the waters that were above the firmament: And it was so. And God called the firmament "heaven." And so of the evening and morning was made the second day.
