Deuteronomy 16:11, 12
and you shall rejoice before the LORD your God in the place He will choose as a dwelling for His Name—you, your sons and daughters, your menservants and maidservants, and the Levite within your gates, as well as the foreigner, the fatherless, and the widows among you. / Remember that you were slaves in Egypt, and carefully follow these statutes.
