Genesis 1:3-5 KJV

And God said, Let there be light: and there was light. [4] And God saw the light, that it was good: and God divided the light from the darkness. [5] And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

Genesis 1:14-19 KJV

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] 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] And God set them in the firmament of the heaven to give light upon the earth, [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.
