Deuteronomy 18:1-3 New Revised Standard Version, Anglicised Catholic Edition (NRSVACE)
Privileges of Priests and Levites
18 The levitical priests, the whole tribe of Levi, shall have no allotment or inheritance within Israel. They may eat the sacrifices that are the Lord’s portion[a] 2 but they shall have no inheritance among the other members of the community; the Lord is their inheritance, as he promised them.
3 This shall be the priests’ due from the people, from those offering a sacrifice, whether an ox or a sheep: they shall give to the priest the shoulder, the two jowls, and the stomach.
