Romans 11:29 (KJV)

For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree?

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 father's sakes.

For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:

Even so have these also now not believed, that through your mercy they also may obtain mercy.

For God hath concluded them all in unbelief, that he might have mercy upon all.

O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!

For who hath known the mind of the Lord? or who hath been his counsellor?
