Ezra 2:62 Meaning and Commentary

Ezra 2:62

These sought their register among those that were reckoned by
genealogy

but they were not found;
their names were not there, nor any account taken of them:

therefore were they, as polluted, put from the priesthood;
were not suffered to attend at the altar, and offer sacrifice, and enjoy the privileges belonging to that office.
