Deuteronomy 16:11, 14-15

and you shall rejoice before the LORD your God, you and your son and your daughter and your male and female servants and the Levite who is in your town, and the stranger and the orphan and the widow who are in your midst, in the place where the LORD your God chooses to establish His name.

and you shall rejoice in your feast, you and your son and your daughter and your male and female servants and the Levite and the stranger and the orphan and the widow who are in your towns. Seven days you shall celebrate a feast to the LORD your God in the place which the LORD chooses, 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.
