Peter asked why they had sent for him.

Acts 10:27-29

27 While he was talking to Cornelius, Peter and the others entered a large room inside the house. Peter saw that many people had gathered together there. 28 Then Peter said to them, “You all know that any of us Jews think we are disobeying our Jewish laws if we (exc) associate with a non-Jewish person or if we even visit him. However, God has shown me in a vision that I should not say about anyone that God will not accept him. 29 So when you sent some men to ask me to come here, I came right away. I did not say that I could not go with non-Jewish people. So, please tell me, why have you asked me to come here?”
