Genesis 2:1 – 3
New King James Version (NKJV)
2 1 Thus the heavens and the earth, and all the host of them, were finished. 2 And on the seventh day God ended His work which He had done, and He rested on the seventh day from all His work which He had done. 3 Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.
