Sh'mot (Exo) 20:8-11

“Remember the day, Shabbat, to set it apart for God. You have six days to labor and do all your work, but the seventh day is a Shabbat for ADONAI your God. On it, you are not to do any kind of work — not you, your son or your daughter, not your male or female slave, not your livestock, and not the foreigner staying with you inside the gates to your property. For in six days, ADONAI made heaven and earth, the sea and everything in them; but on the seventh day he rested. This is why ADONAI blessed the day, Shabbat, and separated it for himself. ה
