Galatians 2:11-14 - Paul Confronts Peter At Antioch
11 But when Peter came to Antioch I opposed him to his face, because he was to blame. 12 For before some came from James he eat with the gentiles; but when they came, he withdrew and separated himself; fearing those of the circumcision; 13 and the other Jews also dissembled with him, so that Barnabas was carried away with their dissimulation. 14 But when I saw that they walked not correctly, according to the truth of the gospel, I said to Peter before all, If you being a Jew live after the manner of the gentiles, and not after the manner of the Jews, why do you compel the gentiles to practise Judaism?
