Genesis 1:6-8

WEB(i) 6 God said, “Let there be an expanse in the middle of the waters, and let it divide the waters from the waters.” 7 God made the expanse, and divided the waters which were under the expanse from the waters which were above the expanse; and it was so. 8 God called the expanse “sky”. There was evening and there was morning, a second day.
