Deuteronomy 12:5-7, 17-18

but look for the place the LORD your God will choose—a place among your tribes where he is to be worshiped. Go there, and bring to that place your burnt offerings and sacrifices; bring a tenth of what you gain and your special gifts; bring what you have promised and the special gifts you want to give the LORD, and bring the first animals born to your herds and flocks. There you will be together with the LORD your God. There you and your families will eat, and you will enjoy all the good things for which you have worked, because the LORD your God has blessed you.

Do not eat in your own towns what belongs to the LORD: one-tenth of your grain, new wine, or oil; the first animals born to your herds or flocks; whatever you have promised to give; the special gifts you want to give to the LORD, or any other gifts. Eat these things when you are together with the LORD your God, in the place the LORD your God chooses to be worshiped. Everyone must do this: you, your sons and daughters, your male and female servants, and the Levites from your towns. Rejoice in the LORD your God’s presence about the things you have worked for.
