“And from thenceforth Pilate sought to release him: but the Jews cried out, saying, If thou let this man go, thou art not Caesar's friend: whosoever maketh himself a king speaketh against Caesar.”
King James Version (KJV)
Joh 19:12 If thou let this man go, thou art not Caesar's friend. This means that he will be accused before Caesar's tribunal of winking at treason. The Caesar then on the throne was Tiberius, dark, suspicious, cruel in character. Such a charge from the representatives of the Jewish nation at Rome would probably prove fatal to Pilate; would certainly end his career as a public man. The risk was too great. He would rather sacrifice an innocent man than to sacrifice himself. Hence he at once surrenders.
