Ezekiel 44:21-23

New Century Version

²¹ None of the priests may drink wine when they enter the inner courtyard. ²² The priests must not marry widows or divorced women. They may marry only virgins from the people of Israel or widows of priests. ²³ They must teach my people the difference between what is holy and what is not holy. They must help my people know what is unclean and what is clean.
