Ezekiel 44:19-29

19 When they go out into the outer court to the people, they shall remove the vestments in which they have been ministering, and lay them in the holy chambers; and they shall put on other garments, so that they may not communicate holiness to the people with their vestments.
20 They shall not shave their heads or let their locks grow long; they shall only trim the hair of their heads.
21 No priest shall drink wine when he enters the inner court.
22 They shall not marry a widow, or a divorced woman, but only a virgin of the stock of the house of Israel, or a widow who is the widow of a priest.
23 They shall teach my people the difference between the holy and the common, and show them how to distinguish between the unclean and the clean.
24 In a controversy they shall act as judges, and they shall decide it according to my judgments. They shall keep my laws and my statutes regarding all my appointed festivals, and they shall keep my sabbaths holy.
25 They shall not defile themselves by going near to a dead person; for father or mother, however, and for son or daughter, and for brother or unmarried sister they may defile themselves.
26 After he has become clean, they shall count seven days for him.
27 On the day that he goes into the holy place, into the inner court, to minister in the holy place, he shall offer his sin offering, says the Lord God.
28 This shall be their inheritance: I am their inheritance; and you shall give them no holding in Israel; I am their holding.
29 They shall eat the grain offering, the sin offering, and the guilt offering; and every devoted thing in Israel shall be theirs.
