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.
That night the Lord stood near him and said, "Keep up your courage! For just as you have testified for me in Jerusalem, so you must bear witness also in Rome."
In the morning the Jews joined in a conspiracy and bound themselves by an oath neither to eat nor drink until they had killed Paul.
There were more than forty who joined in this conspiracy.
They went to the chief priests and elders and said, "We have strictly bound ourselves by an oath to taste no food until we have killed Paul
Now then, you and the council must notify the tribune to bring him down to you, on the pretext that you want to make a more thorough examination of his case. And we are ready to do away with him before he arrives."
Now the son of Paul's sister heard about the ambush; so he went and gained entrance to the barracks and told Paul.
