Ezekiel 44:21-23

King James Version

²¹ Neither shall any priest drink wine, when they enter into the inner court.

²² Neither shall they take for their wives a widow, nor her that is put away: but they shall take maidens of the seed of the house of Israel, or a widow that had a priest before.

²³ And they shall teach my people the difference between the holy and profane, and cause them to discern between the unclean and the clean.
