Deuteronomy 12:11-12

12:11 Then you must come to the place the Lord your God chooses for his name to reside, bringing everything I am commanding you – your burnt offerings, sacrifices, tithes, the personal offerings you have prepared, and all your choice votive offerings which you devote to him. 12:12 You shall rejoice in the presence of the Lord your God, along with your sons, daughters, male and female servants, and the Levites in your villages (since they have no allotment or inheritance with you).

Deuteronomy 12:19

12:19 Be careful not to overlook the Levites as long as you live in the land.
