But when he saw many of the pharisees and sadducees coming to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come?

and therefore when Jesus said to them, Take heed and beware of the leaven of the pharisees and of the sadducees,

And while they were speaking to the people, the priests, and the captain of the temple, and the sadducees came upon them,

Then the high priest rose up, and all that were with him, (being of the sect of the sadducees,) and were filled with rage:

But Paul, knowing that the one part were sadducees, and the other pharisees, cried out in the sanhedrim, "Brethren, I am a pharisee, the son of a pharisee: for the hope of a resurrection of the dead I am now prosecuted."

Which

Now if it be preached that Christ is risen from the dead, how say some among you, that there is no resurrection of the dead?

saying that the resurrection is already past; and subvert the faith of some.

General references

For the sadducees say that there is no resurrection, nor angel, nor spirit; but the pharisees acknowledge both.
