Acts 28:21 - Ellicott's Commentary On The Whole Bible

We neither received letters out of Judsea concerning thee... — It seems strange at first that no tidings should have come from Jerusalem of what had passed there in connection with St. Paul’s imprisonment. There was, however, hardly likely to have been time for any letters since his appeal. He had sailed somewhat late in the autumn, immediately after he had made it (Acts 25:13; Acts 27:1), and all communication by sea was suspended during the winter months. And it may be noted further that the Jews do not say that they had heard absolutely nothing about him, but that those who had come had spoken nothing evil of him. What they had heard by casual rumour may well have been consistent with St. James’s statement that “he walked orderly, and observed the Law” (Acts 21:20). It has been urged that the decree of Claudius had suspended the intercourse between the Jews of Rome and those of Jerusalem; but as the former had returned before he wrote the Epistle to the Romans, this is hardly a tenable explanation. It may, however, be taken into account that among the Jews who had returned to Rome would be not a few of those who had known St. Paul at Corinth, and were willing to bear their testimony to his character.
