Matthew 16:5-12

5Now when His disciples had come to the other side, they had forgotten to take bread.

6Then Jesus said to them, “Take heed and beware of the leaven of the Pharisees and the Sadducees.”

7And they reasoned among themselves, saying, “It is because we have taken no bread.”

8But Jesus, being aware of it, said to them, “O you of little faith, why do you reason among yourselves because you have brought no bread?

9Do you not yet understand, or remember the five loaves of the five thousand and how many baskets you took up?

10Nor the seven loaves of the four thousand and how many large baskets you took up?

11How is it you do not understand that I did not speak to you concerning bread?—but to beware of the leaven of the Pharisees and Sadducees.”

12Then they understood that He did not tell them to beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.
