6 “Hence Pilate sought to release Him.” What is to be understood by the word here used, “hence,” as if he had not been seeking to do so before? Read what precedes, and you will find that he had already for some time been seeking to release Jesus. By the original word, therefore, we are to understand, on this account, that is, for this reason, that he might not contract sin by slaying an innocent man who had been delivered into his hands, even though his sin would be less than that of the Jews, who delivered Him to him to be put to death. “From thence,” therefore, that is, for this reason, that he might not commit such a sin, “he sought” not now for the first time, but from the beginning, “to release Him.”
