Galatians 2:11-14 - Paul Confronts Peter At Antioch
11 But when Peter had come to Antioch, I withstood him to the face, because he was to be blamed. 12 For before that certain came from James, he used to eat with the Gentiles: but when they had come, he withdrew, and separated himself, fearing them who were of the circumcision. 13 And the other Jews dissembled likewise with him; so that Barnabas also was carried away with their dissimulation. 14 But when I saw that they walked not uprightly according to the truth of the gospel, I said to Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
