Matthew 16:5-12 - Beware The Leaven Of The Pharisees And Sadducees
5 The disciples came to the other side and had forgotten to take bread.
6 Jesus said to them, "Take heed and beware of the yeast of the Pharisees and Sadducees."
7 They reasoned among themselves, saying, "We brought no bread."
8 But Jesus, becoming aware of this, said, "You of little faith, why are you discussing among yourselves about having no bread? 9 Do you still not understand? Do you not remember the five loaves for the five thousand, and how many baskets you took up? 10 Nor the seven loaves for the four thousand, and how many baskets you took up? 11 Why is it that you do not understand that I did not speak to you concerning bread? But beware of the yeast of the Pharisees and Sadducees." 12 Then they understood that he did not tell them to beware of the yeast of bread, but of the teaching of the Pharisees and Sadducees.
