Galatians 2:11-13

11But later, when Peter came to Antioch, I spoke against him. I told him clearly that he had done something wrong.

12When he first arrived in Antioch, Peter had been eating meals with the Gentile believers there. Then James sent some Jewish believers from Jerusalem to Antioch. After those men had arrived, Peter started to keep himself separate from the Gentiles. He stopped eating meals with them. He was afraid of those Jews who wanted to circumcise the Gentile believers.

13The other Jewish believers in Antioch also did what Peter did. They became hypocrites like him. Even Barnabas agreed and he copied their example.
