Ezekiel 44:21-23

MSTC(i) 21 All the priests that go in to the inmost court, shall drink no wine. 22 They shall marry no widow, neither one that is put from her husband: but a maiden of the seed of the house of Israel, or a widow that hath had a priest before. 23 They shall show my people the difference between the holy and unholy, betwixt the clean and unclean.
