Deuteronomy 16:13

11You shall rejoice before the LORD your God: you, your son, your daughter, your male servant, your female servant, the Levite who is within your gates, the foreigner, the fatherless, and the widow who are among you, in the place which the LORD your God shall choose to cause his name to dwell there.

12You shall remember that you were a slave in Egypt. You shall observe and do these statutes.

13You shall keep the feast of booths seven days, after you have gathered in from your threshing floor and from your wine press.

14You shall rejoice in your feast, you, your son, your daughter, your male servant, your female servant, the Levite, the foreigner, the fatherless, and the widow who are within your gates.

15You shall keep a feast to the LORD your God seven days in the place which the LORD chooses, because the LORD your God will bless you in all your increase and in all the work of your hands, and you shall be altogether joyful.
