Genesis 1:1
In the beginning, God created the heavens and the earth. ...
So God created man in his own image, in the image of God he created him; male and female he created them....
Genesis 2:2,3 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.
