Joshua 18:7

Provision for Priests and Levites

18:1 The Levitical priests – indeed, the entire tribe of Levi – will have no allotment or inheritance with Israel; they may eat the burnt offerings of the Lord and of his inheritance. 18:2 They will have no inheritance in the midst of their fellow Israelites; the Lord alone is their inheritance, just as he had told them.
