Romans 11:16 (KJV)

I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.

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?

For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:

If by any means I may provoke to emulation them which are my flesh, and might save some of them.

For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?

And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;

Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.

Thou wilt say then, The branches were broken off, that I might be graffed in.

Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:

For if God spared not the natural branches, take heed lest he also spare not thee.
