Exodus 20:8-11

[Earnestly] remember the Sabbath day, to keep it holy (withdrawn from common employment and dedicated to God). Six days you shall labor and do all your work, But the seventh day is a Sabbath to the Lord your God; in it you shall not do any work, you, or your son, your daughter, your manservant, your maidservant, your domestic animals, or the sojourner within your gates. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. That is why the Lord blessed the Sabbath day and hallowed it [set it apart for His purposes].
