MK 14: 53-65 "Then Jesus was taken to the High Priest's house, where all the chief priests, the elders, and the teachers of the Law were gathering....The chief priests and the whole Council tried to find some evidence against Jesus in order to put him to death, but they could not find any. Many witnesses told lies against Jesus, but their stories did not agree. Then some men stood up and told this lie against Jesus: `We heard him say, "I will tear doen this Temple which men have made, and after three days I will build one that is not made by men."' Not even they, however, could make their stories agree. The High Priest stood up in front of them all and questioned Jesus, `Have you no answer to the accusations they bring against you?' But Jesus kept quiet and would not say a word. Again the High Priest questioned him, `Are you the Messiah, the Son of the Blessed God?' `I am,' answered Jesus, `and you will all see the Son of Man seated at the right side of the Almighty and coming with the clouds of heaven!' The High Priest tore his robes and said, `We don't need any more witnesses! You heard his blasphemy. What is your decision?' They all voted against him: he was guilty and should be put to death."
Comment: Jewish law required that two witnesses should independently bring the same charge against a person. This is the reason the Jewish leaders needed two stories that agreed. When asked "Are you the Messiah?" note that only Mark has Jesus responding "I am." Matthew has Jesus answering "The words are yours, (MT 27:11-12)" and Luke has Jesus saying "If I tell you, you will not believe me (LK 23:1-5). In John's gospel, when asked if he was king of the Jews, Jesus gives no direct answer. Also notice that Jesus's response in Mark's gospel is in terms of the "Son of Man," the figure in the book of Daniel.
