Ro 11:12 - Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness?

Paul was always contrasting two groups, the world and the Jew.
RO 11:11 Again I ask: Did they stumble so as to fall beyond recovery? Not at all! Rather, because of their transgression, salvation has come to the Gentiles to make Israel envious. 12
But if their transgression means riches for the world, and their loss means riches for the Gentiles,
how much greater riches will their fullness bring!
