Deuteronomy 12:7, 18

There you and your families will feast in the presence of the LORD your God, and you will rejoice in all you have accomplished because the LORD your God has blessed you.

You must eat these in the presence of the LORD your God at the place he will choose. Eat them there with your children, your servants, and the Levites who live in your towns, celebrating in the presence of the LORD your God in all you do.
