Deuteronomy 16:13-15

The Festival of Temporary Shelters

16:13 You must celebrate the Festival of Temporary Shelters for seven days, at the time of the grain and grape harvest. 16:14 You are to rejoice in your festival, you, your son, your daughter, your male and female slaves, the Levites, the resident foreigners, the orphans, and the widows who are in your villages. 16:15 You are to celebrate the festival seven days before the Lord your God in the place he chooses, for he will bless you in all your productivity and in whatever you do; so you will indeed rejoice!
