Acts 11:2-3

2 Peter then returned from Caesarea and he arrived in Jerusalem. Some of the Jews there who were believers spoke against him. These Jews thought that all believers should be circumcised. 3 So they said to Peter, ‘You stayed in the house of men who were not circumcised. You even ate meals with them!’

11:3The Jews that spoke to Peter believed in Jesus. They thought that Peter had done a wrong thing. He had stayed with people who were not Jews. And he had even eaten meals with them.
