These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens. Genesis 2:4
And God said, Let there be light: and there was light. ... And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. Genesis 1:3 - 2:3
