Genesis 1:6-9

6And God said, “Let there be a vault between the waters to separate water from water.” 7So God made the vault and separated the water under the vault from the water above it. And it was so.

8God called the vault “sky.” And there was evening, and there was morning—the second day. 9And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so.
