Then they understood that He did not say to beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.
How is it that you do not understand that I did not speak to you about loaves, but to beware of the leaven of the Pharisees and of the Sadducees?
But seeing 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 that of the scribes and Pharisees, you shall in no case enter into the kingdom of Heaven.
For the Sadducees say that there is no resurrection, neither angel, nor spirit; but the Pharisees confess both.
Your boasting is not good. Do you not know that a little leaven leavens the whole lump?
