Deuteronomy 5:13-14

Six days you shall labor and do all your work, but the seventh day is a Sabbath [a day of rest dedicated] to the LORD your God; on that day you shall not do any work, you or your son or your daughter or your male servant or your female servant or your ox or your donkey or any of your livestock or the stranger who stays inside your [city] gates, so that your male servant and your female servant may rest as well as you.
