Acts 23:16 - Ellicott's Commentary On The Whole Bible

Paul’s sister’s son. — The passage is note worthy as being the only reference to any of St. Paul’s relations in the Acts. The fact that St. Paul lodged with Mnason, as far as it goes, suggests the probability that neither the sister nor the nephew resided permanently in Jerusalem. We do not even know whether they were members of the Christian society, though this may, perhaps, be inferred from the eagerness of the son to save his uncle from the danger which he know to be imminent. We find that St. Paul had kinsmen at Rome (Romans 16:7; Romans 16:11). Was this nephew one of them who had come to Jerusalem to keep the feast, and heard the plot talked of (it is difficult to keep a secret in which forty men are sharers) in the caravanserai where he and other pilgrims lodged? We see, from the fact thus stated, that St. Paul, though in custody, was allowed to hold free communication with his friends. This, perhaps, accounts for the fulness with which the whole history is given. The writer of the Acts had come up with the Apostle, and was not likely to desert his friend if he could possibly gain access to him.
