The text of the original is appropriately divided here to begin a new chapter, as the apostle enters into a new phase of his argument to prove that the Gospel is absolutely necessary if either Jew or Gentile would be saved.  It is not very easy to deduce precisely to whom he is speaking, as he address “O man,” and says that he is inexcusable for his hypocritical judging of others.  One may think that he is still talking to the generality of mankind, or to the heathen Gentiles whom he has so scorchingly excoriated in the previous verses.  Certainly, the application may justly be made to any person who holds others to a standard by which he does not himself abide.  But it appears to me that the generally given  interpretation for this second chapter is correct; namely, that the apostle, having proven that the Gentiles are utterly depraved, as proved by their estrangement from God, now is turning to the Jews to convince them that they are not secure in their own righteousness, as they may wish to think, but that they too are guilty and condemned before God.  As we proceed throughout the chapter, it will become apparent that Paul is speaking to those who are conversant with the law of God, and fancy that they themselves honor it.  He will go to great lengths to prove that in reality, they are no better than the Gentiles who are aliens from the commonwealth of Israel, because even they have not kept the holy oracles which were given them.
