Romans 11:25-29

So that you may not claim to be wiser than you are, brothers and sisters, I want you to understand this mystery: a hardening has come upon part of Israel, until the full number of the Gentiles has come in. And so all Israel will be saved; as it is written, ‘Out of Zion will come the Deliverer; he will banish ungodliness from Jacob.’ ‘And this is my covenant with them, when I take away their sins.’ As regards the gospel they are enemies of God for your sake; but as regards election they are beloved, for the sake of their ancestors; for the gifts and the calling of God are irrevocable.
