Deuteronomy 12:18-19

18You may only eat these offerings in the place that the Lord will choose as his special home. That is true for you, your children, your servants and the Levites who live in your towns. At that place, you should meet with the Lord your God and you should enjoy the results of all your work.

19As long as you live in the land, be careful to take care of the Levites.
