Genesis 1
14 Ref And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
16 Ref And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
17 Ref And God set them in the firmament of the heaven to give light upon the earth,
18 Ref And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
19 And the evening and the morning were the fourth day.
