Nehemiah 7:62-64

62 the descendants of Delaiah, Tobiah and Nekoda—642.

63 And these priests could not prove that their families came from Israel: the descendants of Hobaiah, Hakkoz and Barzillai. (He had married a daughter of Barzillai from Gilead and was called by her family name.)

64 These people searched for their family records. But they could not find them. So they could not be priests because they were thought to be unclean.
