Theophylact of Ohrid, on Rom 11:23

“And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graft them in again.”

“So too the Jews would have been grafted in, if they had not continued to remain in unbelief; for God did not first cut them off, but they themselves fell away of their own accord and were cut off by their unbelief. In saying that "God did not spare," he means that God does not show mercy to the Jews, but considers them unworthy of communion and fellowship with the holy forefathers. Most wisely Paul frightens the Gentile by what happened to the Jews, while to the Jew, by the example of what happened to the Gentiles, he inspires the boldness to be grafted in by faith and encourages him with hope in the power of God. God is able, he says, to graft them in; He does all things that surpass our hopes.”
