How is it that you do not understand that I did not speak it to you concerning bread, that you should beware of the leaven of the Pharisees and of the Sadducees?
But when he saw many of the Pharisees and Sadducees come to his baptism, he said to them, O generation of vipers, who has warned you to flee from the wrath to come?
For I say to you, That unless your righteousness shall exceed the righteousness of the scribes and Pharisees, you shall by no means enter into the kingdom of heaven.
