They that are of Caesar's household (oi ek th Kaisaro oikia). Not members of the imperial family, but some connected with the imperial establishment. The term can apply to slaves and freedmen and even to the highest functionaries. Christianity has begun to undermine the throne of the Caesars. Some day a Christian will sit on this throne. The gospel works upward from the lower classes. lt was so at Corinth and in Rome. It is true today. It is doubtful if Nero had yet heard of Paul for his case may have been dismissed by lapse of time. But this obscure prisoner who has planted the gospel in Caesar's household has won more eternal fame and power than all the Caesars combined. Nero will commit suicide shortly after Paul has been executed. Nero's star went down and Paul's rose and rises still.
