And when his disciples were come over the water, they had forgotten to take bread. 6Who said to them: Take heed and beware of the leaven of the Pharisees and Sadducees. 7But they thought within themselves, saying: Because we have taken no bread. 8And Jesus knowing it, said: Why do you think within yourselves, O ye of little faith, for that you have no bread? 9Do you not yet understand, neither do you remember the five loaves among five thousand men, and how many baskets you took up? 10Nor the seven loaves, among four thousand men, and how many baskets you took up? 11Why do you not understand that it was not concerning bread I said to you: Beware of the leaven of the Pharisees and Sadducees? 12Then they understood that he said not that they should beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.
