Acts 25:20

Festus pretends, that he knew not by what rule those cases were to be decided, nor before what judges; whether before himself or the Jewish sanhedrim. But this is only his pretension: the true cause why he would not acquit Paul, though he knew him to be innocent, we read, Acts 25:9, viz. that he might do the Jews a pleasure. He asked Paul this question, Whether he would go to Jerusalem? But with a resolution to have sent him whether he would or not, had he not appealed; but then he durst not: for in certain cases none could hinder appeals, from any judge, to the people in the former times, or to their emperor in the latter times.
