When Paul noticed that some were Sadducees and others were Pharisees, he called out in the council, "Brothers, I am a Pharisee, a son of Pharisees. I am on trial concerning the hope of the resurrection of the dead."
When he said this, a dissension began between the Pharisees and the Sadducees, and the assembly was divided.
(The Sadducees say that there is no resurrection, or angel, or spirit; but the Pharisees acknowledge all three.)
Then a great clamor arose, and certain scribes of the Pharisees' group stood up and contended, "We find nothing wrong with this man. What if a spirit or an angel has spoken to him?"
When the dissension became violent, the tribune, fearing that they would tear Paul to pieces, ordered the soldiers to go down, take him by force, and bring him into the barracks.
