511. When did God divide light from darkness?


On the first day of creation.

God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day. - Genesis 1:4-5

On the fourth day.

And God made two great lights; the greater light to rule the day, and the lesser light to rule the night ... to divide the light from the darkness: and God saw that it was good. And the evening and the morning were the fourth day. - Genesis 1:16-19
