Matthew 16:6-12 Douay-Rheims 1899 American Edition (DRA)
6 Who said to them: Take heed and beware of the leaven of the Pharisees and Sadducees.
7 But they thought within themselves, saying: Because we have taken no bread.
8 And Jesus knowing it, said: Why do you think within yourselves, O ye of little faith, for that you have no bread?
9 Do you not yet understand, neither do you remember the five loaves among five thousand men, and how many baskets you took up?
10 Nor the seven loaves among four thousand men, and how many baskets you took up?
11 Why do you not understand that it was not concerning the bread I said to you: Beware of the leaven of the Pharisees and Sadducees?
12 Then they understood that he said not that they should beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.
