Romans 3:2

Much every way: first of all, that they were entrusted with the oracles of God. [To the circumcised Jew God had given the Scriptures. The law, the Psalms, the prophets were his, with all the revelations and promises therein contained. They revealed man's origin, his fall and his promised redemption; they also described the Redeemer who should come, and prepared men to receive him and to believe him. How unspeakable the advantage of the Jew in possessing such a record. But the Jew had not improved this advantage, and so we may regard him as asking the apostle this further question, "But, after all, the greatest part of us have not believed on this Jesus, and so what advantage were our oracles to us in reality?" The apostle now answers this objection.]
