Nehemiah 7:63-65

63And of the priests: the sons of Hobaiah, the sons of Hakkoz, the sons of Barzillai, who took a wife of the daughters of Barzillai, the Gileadite, and was named after them. 64These searched among their ancestral registration, but it could not be located; therefore they were considered unclean and disqualified from the priesthood. 65And 1the 2governor said to them that they were not to eat from the most holy things until a priest arose with 3Urim and Thummim.
