Aristobulus

Aristobulus is mentioned in Romans 16:10, where Paul greets 'those who belong to the household of Aristobulus.' The phrasing implies that Aristobulus himself was not a Christian—or perhaps had already died—but that some members of his household were believers. Several scholars identify this Aristobulus with the grandson of Herod the Great and brother of Herod Agrippa I, who lived in Rome as a private citizen and was a friend of the Emperor Claudius. If this identification is correct, Paul's greeting would be to slaves or freedmen of a well-known Roman-Jewish household who had become Christians.
