Deuteronomy 12:5-7, 17

But you shall seek the LORD at the place which the LORD your God will choose from all your tribes, to establish His name there for His dwelling, and there you shall come. There you shall bring your burnt offerings, your sacrifices, your tithes, the contribution of your hand, your votive offerings, your freewill offerings, and the firstborn of your herd and of your flock. There also you and your households shall eat before the LORD your God, and rejoice in all your undertakings in which the LORD your God has blessed you.

You are not allowed to eat within your gates the tithe of your grain or new wine or oil, or the firstborn of your herd or flock, or any of your votive offerings which you vow, or your freewill offerings, or the contribution of your hand.
