Deuteronomy 18:1-4

1“The Levitical priests, the whole tribe of Levi, will have no portion or inheritance with Israel. They will eat the Lord’s food offerings; that is their inheritance.

2Although Levi has no inheritance among his brothers, the Lord is his inheritance, as he promised him.

3This is the priests’ share from the people who offer a sacrifice, whether it is an ox, a sheep, or a goat; the priests are to be given the shoulder, jaws, and stomach.

4You are to give him the firstfruits of your grain, new wine, and fresh oil, and the first sheared wool of your flock.
