Paul and Barnabas preached the gospel and performed miracles in Iconium.

14  Acts 14:1-3

14 At Iconium Paul and Barnabas went as usual into the Jewish meeting place and spoke very convincingly about the Lord Jesus. As a result, many Jews and also non-Jews believed in Jesus. 2 But some of the Jews refused to believe that message, and told the non-Jews not to believe it. They told the non-Jewish people that the message about Jesus was not true. As a result, some of the non-Jews became angry towards the believers there. 3 So Paul and Barnabas spent considerable time there speaking boldly for the Lord, and the Lord Jesus enabled them to do many miracles. In this way he showed people that the message about how the Lord saves us in a way that we do not deserve is true.
