The day four of Genesis

Then God said: "Let there be lights in the dome of the sky, to separate day from night. Let them mark the fixed times, the days and the years,
15
and serve as luminaries in the dome of the sky, to shed light upon the earth." And so it happened:
16
God made the two great lights, the greater one to govern the day, and the lesser one to govern the night; and he made the stars.
17
God set them in the dome of the sky, to shed light upon the earth,
18
to govern the day and the night, and to separate the light from the darkness. God saw how good it was.
19
Evening came, and morning followed--the fourth day.
