Genesis

1:14 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:
1:15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
1:16 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.
1:17 And God set them in the firmament of the heaven to give light upon the earth,
1:18 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.
1:19 And the evening and the morning were the fourth day.
