Ezra 2:61-63

Of the sons of the priests: the sons of Habaiah, the sons of Hakkoz, the sons of Barzillai, who took a wife from the daughters of Barzillai the Gileadite, and he was called by their name. These searched among their ancestral registration, but they could not be located; therefore they were considered unclean and excluded from the priesthood. The governor said to them that they should not eat from the most holy things until a priest stood up with Urim and Thummim.
