Galatians 2:9-12

9And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.

10Only they would that we should remember the poor; the same which I also was forward to do.

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.
