This is a 45-minute lecture by Dr. Mark Nanos on some translation alternatives in Romans 11 and their implications for Christian-Jewish relations. Dr. Nanos has identified some places in the English translations where the Greek provides other more positive possibilities. Dr. Nanos' religion is Reformed Judaism; he holds a Ph.D. from the University of St. Andrews, Scotland. His studies and his publications and books have been primarily on the writings of Paul.
It is a very good lecture about some very important texts. It is presented in an academic setting and he is assuming that his audience will be comfortable with a little bit of Greek. I think most viewers should have no difficulty in following his points even if they lack any background in Greek.
The link below is to a paper by Dr. Nanos that covers the same general topic as the lecture above.
Images of Jews and Judaism in Paul's Letter to the Romans: Challenging Translation Decisions That Subvert Paul's Message
Romans 11:28-29 is one of the texts that Dr. Nanos discusses in the lecture.
“Concerning the Good News, they are hostile [estranged] for your sake; but concerning chosenness, they are loved on account of the fathers for the gifts and the calling of God are irrevocable.” (Romans 11:28-29 TLV)
