In Corinth, Paul helped many people to become believers.

Acts 18:1-4

18 After that, Paul left Athens city and went to Corinth city. 2 There he met a Jew whose name was Aquila, who grew up in Pontus province. Aquila and his wife Priscilla had recently come from Rome, in Italy. They had previously left Rome because Claudius, the Roman Emperor, had ordered that all the Jews must leave Rome. Paul later went to see Aquila and Priscilla. 3 Those two made tents to earn ◄money/a living►. Paul also made tents, so he stayed with them, and they all worked together. 4 Every Sabbath, Paul went to the Jewish meeting place, where he spoke forcefully to both Jews and non-Jews. He repeatedly tried to persuade them that Jesus is the Messiah.
