9:25-29 The rejecting of the Jews, and the taking in the Gentiles, were foretold in the Old Testament. It tends very much to the clearing of a truth, to observe how the Scripture is fulfilled in it. It is a wonder of Divine power and mercy that there are any saved: for even those left to be a seed, if God had dealt with them according to their sins, had perished with the rest. This great truth this Scripture teaches us. Even among the vast number of professing Christians it is to be feared that only a remnant will be saved.
25. As he saith also in Osee—"Hosea."
I will call them my people, which were not my people; and her beloved, which was not beloved—quoted, though not quite to the letter, from Ho 2:23, a passage relating immediately, not to the heathen, but to the kingdom of the ten tribes; but since they had sunk to the level of the heathen, who were "not God's people," and in that sense "not beloved," the apostle legitimately applies it to the heathen, as "aliens from the commonwealth of Israel and strangers to the covenants of promise" (so 1Pe 2:10).
