Acts 9:19-22

19Afterward he ate some food and regained his strength. Saul stayed with the believers in Damascus for a few days.

20And immediately he began preaching about Jesus in the synagogues, saying, “He is indeed the Son of God!”

21All who heard him were amazed. “Isn’t this the same man who caused such devastation among Jesus’ followers in Jerusalem?” they asked. “And didn’t he come here to arrest them and take them in chains to the leading priests?”

22Saul’s preaching became more and more powerful, and the Jews in Damascus couldn’t refute his proofs that Jesus was indeed the Messiah.
