And God said, Let there be lights in the expanse of the heavens to separate the day from the night, and let them be signs and tokens [of God's provident care], and [to mark] seasons, days, and years, [Gen. 8:22.]
And God made the two great lights–the greater light (the sun) to rule the day and the lesser light (the moon) to rule the night. He also made the stars.
And God made the firmament [the expanse] and separated the waters which were under the expanse from the waters which were above the expanse. And it was so.
