Galatians 2:9-12

9and when James, Cephas, and John, who seemed to be pillars, perceived the grace that had been given to me, they gave me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcised.

10They desired only that we should remember the poor, the very thing which I also was eager to do.

11Now when Peter had come to Antioch, I withstood him to his face, because he was to be blamed;

12for before certain men came from James, he would eat with the Gentiles; but when they came, he withdrew and separated himself, fearing those who were of the circumcision.
