Ezra 2:59-63

Now these were the ones who came up from Tel-melah, Tel-harsha, Cherub, Addan, and Immer, but they were not able to provide evidence of their fathers’ households and their descendants, whether they were of Israel:

the sons of Delaiah, the sons of Tobiah, and the sons of Nekoda, 652. Priests Removed

Of the sons of the priests: the sons of Hobaiah, 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 genealogical registration but they could not be located; so they were considered defiled and excluded from the priesthood.

The governor said to them that they were not to eat from the most holy things until a priest stood up with Urim and Thummim.
