Galatians 2:11-13

11But when Peter was come to Antioch, I withstood him to the face, because he was to be blamed.

12For before that certain came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision.

13And the other Jews dissembled likewise with him; insomuch that Barnabas also was carried away with their dissimulation.
