Acts 23:4-6

Young's Literal Translation

⁴ And those who stood by said, `The chief priest of God dost thou revile?'

⁵ and Paul said, `I did not know, brethren, that he is chief priest: for it hath been written, Of the ruler of thy people thou shalt not speak evil;'

⁶ and Paul having known that the one part are Sadducees, and the other Pharisees, cried out in the sanhedrim, `Men, brethren, I am a Pharisee -- son of a Pharisee -- concerning hope and rising again of dead men I am judged.'
