Luke 2:32

(non occ.) For the Gentiles before the coming of Christ were lying in the deepest darkness, being without the knowledge of God.

(ubi sup.) 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. (ubi sup.) He said therefore, of thy people, signifying that not only was He adored by them, but moreover of them was He born according to the flesh.

(ubi sup.) But Christ coming was made a light to them that sat in darkness, being sore oppressed by the power of the devil, but they were called by God the Father to the knowledge of His Son, Who is the true light.

And well is the enlightening of the Gentiles put before the glory of Israel, because when the fulness of the Gentiles shall have come in, then shall Israel be safe. (Rom 11:26.)

And this salvation he says is to be the light of the Gentiles and the glory of Israel, as it follows, A light to lighten the Gentiles.
