'Light' in the Bible

Then God said, “Let there be light”; and there was light.

God saw that the light was good; and God separated the light from the darkness.

God called the light day, and the darkness He called night. And there was evening and there was morning, one day.

and let them be for lights in the expanse of the heavens to give light on the earth”; and it was so.

God made the two great lights, the greater light to govern the day, and the lesser light to govern the night; He made the stars also.

God placed them in the expanse of the heavens to give light on the earth,

and to govern the day and the night, and to separate the light from the darkness; and God saw that it was good.

As soon as it was light, the men were sent away, they with their donkeys.
