⁶Then God said, “Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.” ⁷Thus 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. ⁸And God called the firmament Heaven. So the evening and the morning were the second day.
