Deuteronomy 12:6-7

12:6 And there you must take your burnt offerings, your sacrifices, your tithes, the personal offerings you have prepared, your votive offerings, your freewill offerings, and the firstborn of your herds and flocks. 12:7 Both you and your families must feast there before the Lord your God and rejoice in all the output of your labor with which he has blessed you.
