Romans 11:9

And if by grace, then it is no longer of works; otherwise grace is no longer grace. But if it is of works, it is no longer grace; otherwise work is no longer work.

What then? That which Israel seeks for, that he didn’t obtain, but the chosen ones obtained it, and the rest were hardened.

According as it is written, “God gave them a spirit of stupor, eyes that they should not see, and ears that they should not hear, to this very day.”

Let their eyes be darkened, that they may not see.

Always keep their backs bent.”

I ask then, did they stumble that they might fall? May it never be! But by their fall salvation has come to the Gentiles, to provoke them to jealousy.

Now if their fall is the riches of the world, and their loss the riches of the Gentiles, how much more their fullness!
