Ezekiel 44:28-31

28“It [their ministry to Me] shall be as an inheritance to them, for I am their inheritance; and you shall give them no property (land) in Israel, for I am their possession.

29They shall eat the grain offering, the sin offering and the guilt offering; and every devoted thing (offering) in Israel [dedicated by a solemn vow to God] shall be theirs.

30The first of all the first fruits of every kind, and every contribution and offering of every kind, from all your contributions and offerings, shall belong to the priests. You shall also give to the priest the first of your coarse meal and bread dough, so that a blessing may rest on your house.

31The priests shall not eat any bird or animal that has died a natural death or has been torn to pieces.
