Deuteronomy 12:17-18

17You must not eat in your own towns the tithe of your grain and new wine and olive oil, or the firstborn of your herds and flocks, or whatever you have vowed to give, or your freewill offerings or special gifts.

18Instead, you are to eat them in the presence of the Lord your God at the place the Lord your God will choose—you, your sons and daughters, your male and female servants, and the Levites from your towns—and you are to rejoice before the Lord your God in everything you put your hand to.
