Galatians 2:15

15 We ourselves are Jews by birth and not Gentile sinners;

Galatians 2:15 In-Context

13 And the other Jews joined him in this hypocrisy, so that even Barnabas was led astray by their hypocrisy.
14 But when I saw that they were not acting consistently with the truth of the gospel, I said to Cephas before them all, "If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?"
15 We ourselves are Jews by birth and not Gentile sinners;
16 yet we know that a person is justified not by the works of the law but through faith in Jesus Christ. And we have come to believe in Christ Jesus, so that we might be justified by faith in Christ, and not by doing the works of the law, because no one will be justified by the works of the law.
17 But if, in our effort to be justified in Christ, we ourselves have been found to be sinners, is Christ then a servant of sin? Certainly not!
