Genesis 2: 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.

Mark 2: 27 And He said to them, “The Sabbath was made for man, and not man for the Sabbath. 28 Therefore the Son of Man is also Lord of the Sabbath.”
