Genesis 1:4; Genesis 1:6; Genesis 1:9

4 And God saw the light, that it was good: and God divided the light from the darkness.
6 And God said , Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
9 And God said , Let the waters under the heaven be gathered together unto one place, and let the dry land appear : and it was so.
