John Calvin on Acts 28:19

19. I was enforced to appeal. This appeal was full of hatred and envy for this cause, because the authority and liberty of the Jewish nation did seem to be sore opprest, who could have been content to have lived with their own laws. Secondly, because his defense was joined with infamy and loss of all the people. Therefore he answereth this objection also, because he was enforced with the stubbornness of his enemies to fly to this fortress [asylum]. For he is excused by necessity, because he had no other way to escape death. And after that he had excused that which was done already, he promiseth that he will so handle his matter hereafter, “Ita causam suam acturum,” will so plead his cause. that he will not labor against the Jews.
