God said, let there be a firmament in the midst of the waters, and let
it divide the waters from the waters. And God made the firmament, and
divided the waters which were under the firmament from the waters which
were above the firmament: and it was so. And God called the firmament
Heaven. And there was evening and there was morning, a second day. This
is the 2nd day of a 7 days journey.
