Galatians 2:11-14

But when Cephas came to Antioch, I opposed him to his face because he stood condemned. For he regularly ate with the Gentiles before certain men came from James. However, when they came, he withdrew and separated himself, because he feared those from the circumcision party. Then the rest of the Jews joined his hypocrisy, so that even Barnabas was led astray by their hypocrisy. But when I saw that they were deviating from the truth of the gospel, I told Cephas in front of everyone, “If you, who are a Jew, live like a Gentile and not like a Jew, how can you compel Gentiles to live like Jews?”
