Ezekiel 44:28-31

28"This shall be their inheritance: I am their inheritance: and you shall give them no possession in Israel; I am their possession.

29They shall eat the grain offering, the sin offering, and the guilt offering, and every devoted thing in Israel shall be theirs.

30And the first of all the firstfruits of all kinds, and every offering of all kinds from all your offerings, shall belong to the priests. You shall also give to the priests the first of your dough, that a blessing may rest on your house.

31The priests shall not eat of anything, whether bird or beast, that has died of itself or is torn by wild animals.
