Israel was enlightened though dimly by the law, so he says not that light came to them, but his words are, to be the glory of thy people Israel. Calling to mind the ancient history, that as of old Moses after speaking with God returned with his face glorious, so they also coming to the divine light of His human nature, casting away their old veil, might be transformed into the same image from glory to glory (2 Cor. 3:7.) For although some of them were disobedient, yet a remnant were saved and came through Christ to glory, of which the Apostles were first-fruits, whose brightness illumines the whole world. For Christ was in a peculiar manner the glory of Israel, because according to the flesh He came forth from Israel, although as God He was over all blessed for ever.
