11and you shall rejoice before the Lord your God, you and your son and your daughter and your male and female servants and the Levite who is within your [city] gates, and the stranger and the orphan and the widow who are among you, at the place where the Lord your God chooses to establish His Name (Presence).

12You shall remember that you were a slave in Egypt, and you shall be careful to obey these statutes.

13“You shall celebrate the Feast of Booths (Tabernacles) seven days, when you have gathered in [the grain] from your threshing floor and [the wine] from your wine vat.

14You shall rejoice in your feast, you and your son and your daughter and your male and female servants and the Levite and the stranger and the orphan and the widow who are within your city.
