Ezra 2:61-62

61These priests also could not show what families they belonged to: The descendants of Hobaiah, Hakkoz and Barzillai. (This Barzillai had married one of the daughters of a man from Gilead called Barzillai. So he took Barzillai's name for himself.)

62These people tried to find their names in the lists of priests' families. But they could not find anything. So they could not serve as priests.
