Then they understood that He did not say to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees.
How is it that you do not understand that I did not speak to you concerning bread? But beware of the leaven of the Pharisees and Sadducees.”
But when he saw many of the Pharisees and Sadducees coming for his baptism, he said to them, “You brood of vipers, who warned you to flee from the wrath to come?
“For I say to you that unless your righteousness surpasses that of the scribes and Pharisees, you will not enter the kingdom of heaven.
For the Sadducees say that there is no resurrection, nor an angel, nor a spirit, but the Pharisees acknowledge them all.
Your boasting is not good. Do you not know that a little leaven leavens the whole lump?
