Galatians 2:11–14

But when Cephas was come to Antioch, I withstood him to the face, because he was to be blamed. 12For before that some came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them who were of the circumcision. 13And to his dissimulation the rest of the Jews consented: so that Barnabas also was led by them into that dissimulation. 14But when I saw that they walked not uprightly unto the truth of the gospel, I said to Cephas before them all: If thou, being a Jew, livest after the manner of the Gentiles and not as the Jews do, how dost thou compel the Gentiles to live as do the Jews?
