Note 1 at Ac 28:20: There were at least two purposes for Paul calling these Jewish leaders together. First, it had been the Jews in Judea who instigated all the turmoil that resulted in Paul's arrest. Again, the Jews were instrumental in keeping him bound when the Romans were determined to let him go (Ac 24:27 and 25:9). Certainly, he wanted to present his case to these Jewish leaders to try to prevent a repeat of that.

Second, Paul had purposed in his spirit to minister to those in Rome, even before the riot and his imprisonment in Jerusalem (Ac 19:21). Therefore, he was simply taking advantage of the situation to share the Gospel with the leaders of the Jewish community. He was successful in obtaining a day when they came together to hear him share the Gospel.
