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.

Deuteronomy 16:11

16:11 You shall rejoice before him – you, your son, your daughter, your male and female slaves, the Levites in your villages, the resident foreigners, the orphans, and the widows among you – in the place where the Lord chooses to locate his name.

Deuteronomy 28:68

28:68 Then the Lord will make you return to Egypt by ship, over a route I said to you that you would never see again. There you will sell yourselves to your enemies as male and female slaves, but no one will buy you.”
