But when he saw many of the Pharisees and Sadducees coming for baptism, he exclaimed, "O vipers' brood, who has warned you to flee from the coming wrath?

and when Jesus said to them, "See to it: beware of the yeast of the Pharisees and Sadducees,"

While they were saying this to the people, the Priests, the Commander of the Temple Guard, and the Sadducees came upon them,

This roused the High Priest. He and all his party--the sect of the Sadducees--were filled with angry jealousy

Noticing, however, that the Sanhedrin consisted partly of Sadducees and partly of Pharisees, he called out loudly among them, "Brethren, I am a Pharisee, the son of Pharisees. It is because of my hope of a resurrection of the dead that I am on my trial."

Which

But if Christ is preached as having risen from the dead, how is it that some of you say that there is no such thing as a resurrection of the dead?

In the matter of the truth they have gone astray, saying that the Resurrection is already past, and so they are overthrowing the faith of some.

General references

For the Sadducees maintain that there is no resurrection, and neither angel nor spirit; but the Pharisees acknowledge the existence of both.
