In The Beginning

6 Then God said, “Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.” 7 Thus 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. 8 And God called the firmament Heaven. So the evening and the morning were the second day.
9 Then God said, “Let the waters under the heavens be gathered together into one place, and let the dry land appear”; and it was so. 10 And God called the dry land Earth, and the gathering together of the waters He called Seas. And God saw that it was good.
