Genesis 1:14-19 CEB
God said, “Let there be lights in the dome of the sky to separate the day from the night. They will mark events, sacred seasons, days, and years. They will be lights in the dome of the sky to shine on the earth.” And that’s what happened. God made the stars and two great lights: the larger light to rule over the day and the smaller light to rule over the night. God put them in the dome of the sky to shine on the earth, to rule over the day and over the night, and to separate the light from the darkness. God saw how good it was.
There was evening and there was morning: the fourth day.
