Ezra 2:61-62
Also, of the sons of the priests: the sons of Habaiah, the sons of Hakkoz, and the sons of Barzillai (who had taken a wife from the daughters of Barzillai the Gileadite, and was called by their name). These sought their registration among those enrolled in the genealogies, but they were not found there, and so they were excluded from the priesthood as unclean.
