Genesis 1:6 DBY

⁴  And God saw the light that it was good; and God divided between the light and the darkness.

⁵  And God called the light Day, and the darkness he called Night. And there was evening, and there was morning -- the first day.

⁶  And God said, Let there be an expanse in the midst of the waters, and let it be a division between waters and waters.

⁷  And God made the expanse, and divided between the waters that are under the expanse and the waters that are above the expanse; and it was so.

⁸  And God called the expanse Heavens. And there was evening, and there was morning -- a second day.
