Appeal in the Bible

Acts 25:10-11 Then said Paul, I stand at Caesar's judgment seat, where I ought to be judged: to the Jews have I done no wrong, as thou very well knowest. 11 For if I be an offender, or have committed any thing worthy of death, I refuse not to die: but if there be none of these things whereof these accuse me, no man may deliver me unto them. I appeal unto Caesar.
Acts 25:21-27 But when Paul had appealed to be reserved unto the hearing of Augustus, I commanded him to be kept till I might send him to Caesar. 22 Then Agrippa said unto Festus, I would also hear the man myself. To morrow, said he, thou shalt hear him. 23 And on the morrow, when Agrippa was come, and Bernice, with great pomp, and was entered into the place of hearing, with the chief captains, and principal men of the city, at Festus' commandment Paul was brought forth. 24 And Festus said, King Agrippa, and all men which are here present with us, ye see this man, about whom all the multitude of the Jews have dealt with me, both at Jerusalem, and also here, crying that he ought not to live any longer. ...
Acts 26:32 Then said Agrippa unto Festus, This man might have been set at liberty, if he had not appealed unto Caesar.
Acts 28:19 But when the Jews spake against it, I was constrained to appeal unto Caesar; not that I had ought to accuse my nation of.
