Galatians 2:9-11 Common English Bible (CEB)
9 James, Cephas, and John, who are considered to be key leaders, shook hands with me and Barnabas as equals when they recognized the grace that was given to me. So it was agreed that we would go to the Gentiles, while they continue to go to the people who were circumcised. 10 They asked only that we would remember the poor, which was certainly something I was willing to do.
The Jewish-Gentile controversy
11 But when Cephas came to Antioch, I opposed him to his face, because he was wrong.
