Ezekiel — Chapter 42
The chambers (exedrae) for the priests, where they eat the most holy things and change their garments. Lapide reads the priests' chambers as a type of the contemplative life — withdrawal from the outer courts of active ministry to feed on the most sacred truths. The changing of garments symbolizes the theological virtues replacing natural character.
Verse 13
The priests shall eat the most holy offerings there: Lapide's sacramental reading — the innermost chamber where priests eat the most holy things images the priest's reception of the Eucharist, the most holy of all sacrifices. He cites Trent's teaching on the Mass as sacrifice and the priest as its primary participant, and discusses the rubrics of eucharistic reception.
