Galatians 2:10

8for he who worked through Peter in the apostleship with the circumcised also worked through me with the Gentiles—

9and when they perceived the grace that was given to me, James and Cephas and John, those who were reputed to be pillars, gave to Barnabas and me the right hand of fellowship, that we should go to the Gentiles, and they to the circumcision.

10They only asked us to remember the poor—which very thing I was also zealous to do.

11But when Peter came to Antioch, I resisted him to his face, because he stood condemned.

12For before some people came from James, he ate with the Gentiles. But when they came, he drew back and separated himself, fearing those who were of the circumcision.
