Romans 11:25-29

For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.

And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:

For this is my covenant unto them, when I shall take away their sins.

As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers’ sakes.

For the gifts and calling of God are without repentance.
