Robertson's Word Pictures (NT)
This man might have been set at liberty (Apolelusqai edunato o anqrwpov outov). Conclusion of the second class condition (determined as unfulfilled) without an as in Acts 24:19 because of edunato (verb of possibility, Robertson, Grammar, p. 1014). Note perfect passive infinitive apolelusqai from apoluw. He certainly "could have been set free." Why was it not done?
If he had not appealed unto Caesar (ei mh epekeklhto Kaisara). Condition of the second class with the past perfect middle indicative (op. cit., p. 1015) of epikalew (cf. Acts 25:11 f.). But Paul only appealed to Caesar after Festus had tried to shift him back to Jerusalem and had refused to set him free in Caesarea. Festus comes out with no honour in the case. Since Agrippa was a favourite at court perhaps Festus would be willing to write favourably to Caesar.
