Deuteronomy 18:1-5
1
Offerings for Priests and Levites
The priests, who are Levites—indeed the whole tribe of Levi—are to have no allotment or inheritance with Israel. They shall live on the offerings made to the Lord by fire, for that is their inheritance.
2 They shall have no inheritance among their brothers; the Lord is their inheritance, as he promised them.
3 This is the share due the priests from the people who sacrifice a bull or a sheep: the shoulder, the jowls and the inner parts.
4 You are to give them the firstfruits of your grain, new wine and oil, and the first wool from the shearing of your sheep,
5 for the Lord your God has chosen them and their descendants out of all your tribes to stand and minister in the Lord’s name always.
