Later the same day some Sadducees came to see him. (They are the ones who say there's no resurrection.)
“Watch out for the yeast of the Pharisees and Sadducees,” Jesus told them.
But when John saw many of the Pharisees and Sadducees coming to be baptized, he said to them, “You vipers' brood! Who warned you to run away from the coming judgment?
While they were talking to the people, the priests, the captain of the Temple guard, and the Sadducees came up to them.
However, the high priest and those with him (who were Sadducees) became very jealous and decided to intervene.
They have deviated from the truth by saying that the resurrection has already happened, which has ruined some people's trust in God.
