Ezekiel 44:24

20 They must not shave their heads or let their hair grow long, but must carefully trim their hair.

21 No priest may drink wine before he enters the inner court.

22 And they shall not marry a widow or a divorced woman, but must marry a virgin of the descendants of the house of Israel, or a widow of a priest.

23 They are to teach My people the difference between the holy and the common, and show them how to discern between the clean and the unclean.

24 In any dispute, they shall officiate as judges and judge according to My ordinances. They must keep My laws and statutes regarding all My appointed feasts, and they must keep My Sabbaths holy.

25 A priest must not defile himself by going near a dead person. However, for a father, a mother, a son, a daughter, a brother, or an unmarried sister, he may do so,

26 and after he is cleansed, he must count off seven days for himself.

27 And on the day he goes into the sanctuary, into the inner court, to minister in the sanctuary, he must present his sin offering, declares the Lord GOD.

28 In regard to their inheritance, I am their inheritance. You are to give them no possession in Israel, for I am their possession.
