New Defender's Study Bible Notes
23:16 Paul’s sister’s son. This is the only reference in the Bible to the fact that Paul had a sister and nephew. There is no indication as to what they were doing in Jerusalem (Paul’s family originally lived in Tarsus, in Asia Minor), or what access this young man had to the conspirators. As intriguing as such questions are, we can only conclude that all of these circumstances had somehow been ordered in God’s providence to save Paul’s life.
