And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
All Commentaries on Genesis 1:5 Go To Genesis 1
Augustine of Hippo
“And God divided the light and the darkness, and God called the light day and he called the darkness night.” It did not say here “God made the darkness,” because darkness is merely the absence of light. Yet God made a division between light and darkness. So too we make a sound by crying out, and we make a silence by not making a sound, because silence is the cessation of sound. Still in some sense we distinguish between sound and silence and call the one sound and the other silence…. “He called the light day, and he called the darkness night” was said in the sense that he made them to be called, because he separated and ordered all things so that they could be distinguished and receive names. .
