Genesis - The Course: Day 4

And God said, "Let there be luminaries in the expanse of the heavens, to separate between the day and between the night, and they shall be for signs and for appointed seasons and for days and years.  And they shall be for luminaries in the expanse of the heavens to shed light upon the earth." And it was so.  And God made the two great luminaries: the great luminary to rule the day and the lesser luminary to rule the night, and the stars. And God placed them in the expanse of the heavens to shed light upon the earth. And to rule over the day and over the night, and to separate between the light and between the darkness, and God saw that it was good. And it was evening, and it was morning, a fourth day.
