Galatians 2:11-13

But when Cephas came to Antioch, I resisted him to the face, because he stood condemned. For before that certain came from James, he ate with the Gentiles; but when they came, he drew back and separated himself, fearing them that were of the circumcision. And the rest of the Jews dissembled likewise with him; insomuch that even Barnabas was carried away with their dissimulation.
