Ezekiel 44:19-23

And when they go out into the outer courtyard, into the outer courtyard to the people, they shall take off their garments in which they have been ministering and lay them in the holy chambers; then they shall put on other garments, so that they will not transfer holiness to the people with their garments.

Also they shall not shave their heads, yet they shall not let their locks grow long; they shall only trim the hair of their heads.

Nor shall any of the priests drink wine when they enter the inner courtyard.

And they shall not marry a widow or a divorced woman, but shall take virgins from the descendants of the house of Israel, or a widow who is the widow of a priest.

Moreover, they shall teach My people the difference between the holy and the common, and teach them to distinguish between the unclean and the clean.
