Deuteronomy 12:18-19

12:18 Only in the presence of the Lord your God may you eat these, in the place he chooses. This applies to you, your son, your daughter, your male and female servants, and the Levites in your villages. In that place you will rejoice before the Lord your God in all the output of your labor. 12:19 Be careful not to overlook the Levites as long as you live in the land.
