Römer 11:31

Even so have these--the Jews. now not believed--or, "now been disobedient" that through your mercy--the mercy shown to you. they also may obtain mercy--Here is an entirely new idea. The apostle has hitherto dwelt upon the unbelief of the Jews as making way for the faith of the Gentiles--the exclusion of the one occasioning the reception of the other; a truth yielding to generous, believing Gentiles but mingled satisfaction. Now, opening a more cheering prospect, he speaks of the mercy shown to the Gentiles as a means of Israel's recovery; which seems to mean that it will be by the instrumentality of believing Gentiles that Israel as a nation is at length to "look on Him whom they have pierced and mourn for Him," and so to "obtain mercy." (See Co2 3:15-16).

The apostle, having reconciled that great truth of the rejection of the Jews with the promise made unto the fathers, is, in this chapter, further labouring to mollify the harshness of it, and to reconcile it to the divine goodness in general. It might be said, "Hath God then cast away his people?" The apostles therefore sets himself, in this chapter, to make a reply to this objection, and that two ways: - I. He shows at large what the mercy is that is mixed with this wrath (v. 1-32). II. He infers thence the infinite wisdom and sovereignty of God, with the adoration of which he concludes this chapter and subject (Rom 11:33-36).
