John Calvin on Acts 23:27-28

27. This man being taken. This was spoken odiously concerning the Jews, that he might purchase more favor for Paul, that a man, being a Roman, was by them sore beaten, and almost slain; also, he commendeth him for the right and privilege of his freedom, that he may be the more courteously handled. Furthermore, this commendation was not purchased by prayer or flattery, neither was it bought with money. How came it to pass, then, that the chief captain did show himself so courteous freely to an obscure man, and whom all men did hate, save only because the Lord had appointed him to be his servant’s patron? Therefore, we see how he governeth the tongues and hands of the infidels to the profit of those that be his.
