Deuteronomy 12:6-8

6There you shall bring your burnt offerings, your sacrifices, your tithes, the contribution of your hand, your votive (pledged, vowed) offerings, your freewill (voluntary) offerings, and the firstborn of your herd and of your flock.

7And there you and your households shall eat before the Lord your God, and rejoice in all to which you put your hand, in which the Lord your God has blessed you.

8“You shall not do at all what we are doing here [in the camp] today, every man doing whatever is right in his [own] eyes.
