Ezekiel 44:21-23

²¹ No priest shall drink wine when he enters the inner court. ²² They shall not marry a widow, or a divorced woman, but only a virgin of the stock of the house of Israel, or a widow who is the widow of a priest. ²³ They shall teach my people the difference between the holy and the common, and show them how to distinguish between the unclean and the clean.
