Exodus 20:8-11

Remember the Sabbath day and treat it as holy. Six days you may work and do all your tasks, but the seventh day is a Sabbath to the LORD your God. Do not do any work on it—not you, your sons or daughters, your male or female servants, your animals, or the immigrant who is living with you. Because the LORD made the heavens and the earth, the sea, and everything that is in them in six days, but rested on the seventh day. That is why the LORD blessed the Sabbath day and made it holy.
