Deuteronomy 16:11-15

And you shall rejoice before the LORD your God, you and your son and your daughter, your male servant and your female servant, the Levite who is within your towns, the sojourner, the fatherless, and the widow who are among you, at the place that the LORD your God will choose, to make his name dwell there. You shall remember that you were a slave in Egypt; and you shall be careful to observe these statutes. “You shall keep the Feast of Booths seven days, when you have gathered in the produce from your threshing floor and your winepress. You shall rejoice in your feast, you and your son and your daughter, your male servant and your female servant, the Levite, the sojourner, the fatherless, and the widow who are within your towns. For seven days you shall keep the feast to the LORD your God at the place that the LORD will choose, because the LORD your God will bless you in all your produce and in all the work of your hands, so that you will be altogether joyful.
