“We are actually talking about the blessings of Deuteronomy coming to the Gentile nations that have received the Messiah of the Jews. These Gentile nations will consequently become the head, and not the tail, and Paul knew that this was a strategy that would actually work on his people. Carping envy from Gentiles only reinforces Jewish unbelief. It feeds and nourishes Jewish unbelief. It is a central complicating part of the problem of Jewish unbelief.”
