The Jewish leaders asked Paul to tell them about Christianity.

Acts 28:17-22

17 After Paul had been there three days, he sent a message to the Jewish leaders to come and talk with him. So they came, and Paul said to them, “My fellow Jews, although I have not opposed our people nor spoken against the customs of our ancestors, our leaders in Jerusalem seized [MTY] me. But before they could kill me, a Roman commander rescued me and later sent me to Caesarea for Roman authorities/officials to put me on trial. 18 The Roman authorities/officials questioned me and wanted to release me, because I had not done any bad thing for which I should be executed {they should kill me}. 19 But when the Jewish leaders [SYN] there opposed what the Roman authorities wanted to do, I had to formally request that the Emperor judge me here in Rome. But my reason for doing that was not that I wanted to accuse our leaders about anything. 20 So I have requested you to come here so that I can tell you why I am a prisoner. It is because I believe in [MTY] our Messiah, the one God long ago promised to send to us (inc) Jews.” 21 Then the Jewish leaders said, “We (exc) have not received any letters from our fellow Jews in Judea about you. Also, none of our fellow Jews who have arrived here from Judea has said anything bad about you. 22 But we (exc) want to hear what you (sg) think about this Christian sect/group, because we know that in many places [HYP] bad things are being said {people are saying bad things} about it.”
