Acts 23:6-7

6 But when Paul perceived that one part were Sadducees and the other Pharisees, he cried out in the council, "Men and brethren, I am a Pharisee, the son of a Pharisee; concerning the hope and resurrection of the dead I am being judged!"

7 And when he had said this, a dissension arose between the Pharisees and the Sadducees; and the assembly was divided.
