The High Priest and most of the Great Sanhedrin didn't see Jesus as the messiah. They wanted a messiah who they could control. So they refused to listen to what the scriptures had to say. They refused to listen to what the Jewish people had to say. They refused to listen to what their own spies had to say about the miracles that Jesus did. They had accused Jesus of being Devil possessed so He could heal people. And how dare Jesus heal the man with the crippled arm on the Sabbath, though no one ever did anything like that before.
