(Ex 20, 8-11) Remember to keep holy the sabbath day
 "Remember to keep holy the sabbath day.  Six days you may labor and do all your work,  but the seventh day is the sabbath of the LORD, your God. No work may be done then either by you, or your son or daughter, or your male or female slave, or your beast, or by the alien who lives with you.  In six days the LORD made the heavens and the earth, the sea and all that is in them; but on the seventh day he rested. That is why the LORD has blessed the sabbath day and made it holy.
