Nehemiah 7:63-65

63Of the priests: the sons of 1Hobaiah, 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 excluded from the priesthood. 652The 3governor said to them that they should not eat from the most holy things until a priest arose with 4Urim and Thummim.
