Ezekiel 44:23-31

44:23 Moreover, they will teach my people the difference between the holy and the common, and show them how to distinguish between the ceremonially unclean and the clean.

44:24 “‘In a controversy they will act as judges; they will judge according to my ordinances. They will keep my laws and my statutes regarding all my appointed festivals and will observe my Sabbaths.

44:25 “‘They must not come near a dead person or they will be defiled; however, for father, mother, son, daughter, brother or sister, they may defile themselves. 44:26 After a priest has become ceremonially clean, they must count off a period of seven days for him. 44:27 On the day he enters the sanctuary, into the inner court to serve in the sanctuary, he must offer his sin offering, declares the sovereign Lord.

44:28 “‘This will be their inheritance: I am their inheritance, and you must give them no property in Israel; I am their property. 44:29 They may eat the grain offering, the sin offering, and the guilt offering, and every devoted thing in Israel will be theirs. 44:30 The first of all the first fruits and all contributions of any kind will be for the priests; you will also give to the priest the first portion of your dough, so that a blessing may rest on your house. 44:31 The priests will not eat any bird or animal that has died a natural death or was torn to pieces by a wild animal.
