Thou hast said (su eipa). This is a Greek affirmative reply. Mark ( Mark 14:62 ) has it plainly, "I am" (eimi). But this is not all that Jesus said to Caiaphas. He claims that the day will come when Jesus will be the Judge and Caiaphas the culprit using the prophetic language in Daniel 7:13 and Psalms 109:1 . It was all that Caiaphas wanted.
