Deuteronomy 16:11-14

Rejoice before the LORD your God at the place he will choose to be worshiped. Everybody should rejoice: you, your sons and daughters, your male and female servants, the Levites in your town, the strangers, orphans, and widows living among you. Remember that you were slaves in Egypt, and carefully obey all these laws. Celebrate the Feast of Shelters for seven days, after you have gathered your harvest from the threshing floor and winepress. Everybody should rejoice at your Feast: you, your sons and daughters, your male and female servants, the Levites, strangers, orphans, and widows who live in your towns.
