The listeners — both Jews and god-fearing Gentiles — wanted more out of Paul after his initial gospeling in Pisidian Antioch.
13:42 As Paul and Barnabas were going out, the people were urging them to speak about these things on the next Sabbath. 13:43 When the meeting of the synagogue had broken up, many of the Jews and God-fearing proselytes followed Paul and Barnabas, who were speaking with them and were persuading them to continue in the grace of God.
13:44 On the next Sabbath almost the whole city assembled together to hear the word of the Lord. 13:45 But when the Jews saw the crowds, they were filled with jealousy, and they began to contradict what Paul was saying by reviling him. 13:46 Both Paul and Barnabas replied courageously, “It was necessary to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we are turning to the Gentiles. 13:47 For this is what the Lord has commanded us: ‘I have appointed you to be a light for the Gentiles, to bring salvation to the ends of the earth.‘” 13:48 When the Gentiles heard this, they began to rejoice and praise the word of the Lord, and all who had been appointed for eternal life believed. 13:49 So the word of the Lord was spreading through the entire region. 13:50 But the Jews incited the God-fearing women of high social standing and the prominent men of the city, stirred up persecution against Paul and Barnabas, and threw them out of their region. 13:51 So after they shook the dust off their feet in protest against them, they went to Iconium. 13:52 And the disciples were filled with joy and with the Holy Spirit.
