Genesis 1:5-7

New Revised Standard Version Catholic Edition

⁵ 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 a dome in the midst of the waters, and let it separate the waters from the waters.” ⁷ So God made the dome and separated the waters that were under the dome from the waters that were above the dome. And it was so.
