Exodus 20:9-11

9 aSix days you shall labor, and do all your work, 10but the bseventh day is a Sabbath to the  Lord your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the csojourner who is within your gates. 11For din six days the  Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the  Lord blessed the Sabbath day and made it holy.
