And God saw the light, that it was good: and God divided the light from the darkness.

And God called the light Day, and the darkness he called Night. And there was evening and there was morning, one day.

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.

And when the sun was going down, a deep sleep fell upon Abram; and, lo, a horror of great darkness fell upon him.
