"Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath to the LORD your God. On it you shall not do any work, neither you, nor you son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. For in six day the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore, the LORD blessed the Sabbath and made it holy [set apart]."
- Exodus 20:8-11
