Genesis 2:1-4

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. These are the generations of the heavens and the earth when they were created, in the day that the LORD God made the earth and the heavens.
