Ezekiel 44:21

17 When they enter the gates of the inner court, they are to wear linen garments; they must not wear anything made of wool when they minister at the gates of the inner court or inside the temple.

18 They are to wear linen turbans on their heads and linen undergarments around their waists. They must not wear anything that makes them perspire.

19 When they go out to the outer court, to the people, they are to take off the garments in which they have ministered, leave them in the holy chambers, and dress in other clothes so that they do not transmit holiness to the people with their garments.

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,
