They sailed to Perga in Pamphylia. John Mark left them and returned to Jerusalem. Paul and Barnabas went on to Pisidian Antioch. On Sabbath they went to the synagogue. The leaders invited them to speak. Paul reviewed Israelite history from life in Egypt to King David. He introduced Jesus as a descendant of David brought to Israel by God. He said that his team came to town to bring the message of salvation. He recounted the story of Jesus' death and resurrection. He quoted from the Septuagint to assert that Jesus was the promised Christos who brought them forgiveness for their sins. Both the Jews and the "God-fearing" Gentiles invited them to talk more next Sabbath. At that time almost the whole city gathered. This upset some influential Jews who spoke against them. Paul used the occasion to announce a change in his mission which from then on would be to the Gentiles.
