Genesis 1:31–2:3

31 And God saw everything that he had made, and behold, it was very good. And there was evening and there was morning, the sixth day.

The Seventh Day, God Rests

Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done. So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation.
