Galatians 2:11-14 - Paul Confronts Peter At Antioch
11 And when Peter was come to Antioch, I withstood him in the face, for he was worthy to be blamed. 12 For yer that certain came from James, he ate with the gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision, 13 and the other Jews dissembled likewise; Insomuch that Barnabas was brought into their simulation also. 14 But when I saw that they went not the right way after the truth of the gospel, I said unto Peter, before all men, "If thou, being a Jew, livest after the manner of the gentiles, and not as do the Jews: why causest thou the gentiles to live as do the Jews?"
