Pilate (as profane persons use to do) thought that our Saviour, speaking of truth, and a spiritual kingdom, did but cant, and therefore asking him what he meant by truth, he never stays for an answer, but goes out again to the Jews, whom he had left without the door of the judgment hall, and tells them he found no fault in him. Whatever the quality of the kingdom was of which our Saviour spake, he judged that his pretensions to it were not prejudicial to the authority of the emperor, nor the tranquillity of the state, and would have demissed him from their unjust prosecution.
