Ezekiel 44:21

19When they go out into the outer court, even into the outer court to the people, they shall put off their garments in which they minister and lay them in the holy rooms. They shall put on other garments, that they not sanctify the people with their garments.

20“‘“They shall not shave their heads, or allow their locks to grow long. They shall only cut off the hair of their heads.

21None of the priests shall drink wine when they enter into the inner court.

22They shall not take for their wives a widow, or her who is put away; but they shall take virgins of the offspring of the house of Israel, or a widow who is the widow of a priest.

23They shall teach my people the difference between the holy and the common, and cause them to discern between the unclean and the clean.
