Galatians 2:10-12 New Revised Standard Version (NRSV)
10 They asked only one thing, that we remember the poor, which was actually what I was[a] eager to do.
Paul Rebukes Peter at Antioch
11 But when Cephas came to Antioch, I opposed him to his face, because he stood self-condemned; 12 for until certain people came from James, he used to eat with the Gentiles. But after they came, he drew back and kept himself separate for fear of the circumcision faction.
