Genesis 1:3-5
Genesis 1:3-5 AMP
And God said, “Let there be light”; and there was light. God saw that the light was good (pleasing, useful) and He affirmed and sustained it; and God separated the light [distinguishing it] from the darkness. [2 Cor 4:6] And God called the light day, and the darkness He called night. And there was evening and there was morning, one day.
