6 And Jesus said to them, See and beware of the leaven of the Pharisees and Sadducees.
7 And they reasoned among themselves, saying, Because we have taken no bread.
8 And Jesus knowing it, said, Why reason ye among yourselves, O ye of little faith, because ye have taken no bread?
9 Do ye not yet understand nor remember the five loaves of the five thousand, and how many hand-baskets ye took up?
10 nor the seven loaves of the four thousand, and how many baskets ye took up?
11 How do ye not understand that it was not concerning bread I said to you, Beware of the leaven of the Pharisees and Sadducees?
12 Then they comprehended that he did not speak of being beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.
