Genesis 1:5

³  And God said, Let there be light: and there was light.

⁴  And God saw the light, that it was good: and God divided the light from the darkness.

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

⁶  And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.

⁷  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.
