Ezra 2:61-62

61Of the sons of the priests: the sons of Hobaiah, the sons of Hakkoz, the sons of 1Barzillai, who took a wife from the daughters of Barzillai the Gileadite, and he was called by their name.

62These searched among their genealogical registration but they could not be located; 2so they were considered defiled and excluded from the priesthood.
