Romans 11:26

Here is a third and chief part of the aforementioned mystery, that in the end, all Israel shall be saved. By Israel is not meant the whole church of God, consisting of Jews and Gentiles; so that word is used, Galatians 6:16, and elsewhere; for then, what he spake would have been no mystery at all: but by Israel here (as in the precedent verse) you must understand, the nation and people of the Jews. And by all Israel is not meant every individual Israelite, but many, or (it may be) the greatest part of them. So all is to be taken in Scripture: see 1 Thessalonians 6:45 1 Timothy 2:6, and elsewhere. Look, as when he speaks of the conversion of the Gentiles, and the coming in of their fulness, there are many (too many of them) still unconverted; so, notwithstanding the general calling of the Jews, a great many of them may remain uncalled. As it is written; the apostle had this by revelation, but he proves it also by Scripture. All are not agreed from whence these testimonies are taken; the former is found (with some little variation) in Isaiah 59:20: as for the latter, some think it is taken from Jeremiah 31:33. Others think, that he joineth two places in Isaiah together, (as he did before, Romans 11:8), and the last words are taken out of Isaiah 27:9. The Seventy have the very words used by the apostle. These prophecies and promises, though they were in part fulfilled when Christ came in the flesh, \see Acts 3:26\ yet there will be a more full and complete accomplishment thereof upon the Jewish nation and people towards the end of the world.
