Romans 11:26-29

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.
