Exodus 23:12

23:12 For six days you are to do your work, but on the seventh day you must cease, in order that your ox and your donkey may rest and that your female servant’s son and any hired help may refresh themselves.

Deuteronomy 5:14

5:14 but the seventh day is the Sabbath of the Lord your God. On that day you must not do any work, you, your son, your daughter, your male slave, your female slave, your ox, your donkey, any other animal, or the foreigner who lives with you, so that your male and female slaves, like yourself, may have rest.
