Nehemiah 7:64

These sought the pedigree of their company, and it was not found, and they were removed [as polluted] from the priesthood.

These sought their register among those that were reckoned by genealogy, but it was not found: therefore were they, as polluted, put from the priesthood.

These searched for their genealogical records, but couldn’t find them. Therefore they were deemed disqualified and removed from the priesthood.
