Romans 11:8-10

According as it is written— We need not suppose that the Apostle quotes these passages of Scripture as if they predicted the blindness and obduracy of the Jews in his time. It is sufficient for his purpose, if the case of wicked Jews in former ages shews the true reason of the infidelity, obstinacy, and wretchedness of the Jews who rejected the Gospel: for that is the point in view; not to prove that the infidel Jews were blinded,—which was but too evident from their bitter opposition to the Gospel, and so wanted no proof; but to shew them the malignant cause and direful effects of their unbelief.
