Deuteronomy 16:11-14

11and you shall 1rejoice before the Lord your God, you, your son and your daughter, and your male and female slaves, and 2the Levite who is in your 3town, and 4the stranger, the 5orphan, and the widow who are in your midst, at the place where the Lord your God chooses to establish His name. 126You shall also remember that you were a slave in Egypt, and you shall be careful and 7comply with these statutes.

13“8You shall 9celebrate the Feast of 10Booths for seven days when you have gathered in from your threshing floor and your wine vat; 14and you shall 11rejoice in your feast, you, your son and your daughter, and your male and female slaves, and the Levite, the stranger, the 12orphan, and the widow who are in your 13towns.
