Gal 2:11-14
11 But when Peter was come to Antioch, I withstood him to the face, because he
was to be blamed.
12 For 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.
13 And the other Jews dissembled likewise with him; insomuch that Barnabas also
was carried away with their dissimulation.
14 But when I saw that they walked not uprightly according to the truth of the
gospel, I said unto Peter before them all, If thou, being a Jew, livest after
the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles
to live as do the Jews?
(KJV)
