Exodus 20:9-11

You have six days each week for your ordinary work, but the seventh day is a Sabbath day of rest dedicated to the LORD your God. On that day no one in your household may do any work. This includes you, your sons and daughters, your male and female servants, your livestock, and any foreigners living among you. For in six days the LORD made the heavens, the earth, the sea, and everything in them; but on the seventh day he rested. That is why the LORD blessed the Sabbath day and set it apart as holy.
