Romans 11:11-12, 17, 23-24

So I ask: When the Jews fell, did that fall destroy them? No! But their failure brought salvation to those who are not Jews, in order to make the Jews jealous. The Jews’ failure brought rich blessings for the world, and the Jews’ loss brought rich blessings for the non-Jewish people. So surely the world will receive much richer blessings when enough Jews become the kind of people God wants.

It is as if some of the branches from an olive tree have been broken off. You non-Jewish people are like the branch of a wild olive tree that has been joined to that first tree. You now share the strength and life of the first tree, the Jews.

And if the Jews will believe in God again, he will accept them back. God is able to put them back where they were. It is not natural for a wild branch to be part of a good tree. And you who are not Jews are like a branch cut from a wild olive tree and joined to a good olive tree. But since those Jews are like a branch that grew from the good tree, surely they can be joined to their own tree again.
