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 Jesus, perceiving it, said, "Why do you reason among yourselves, you of little faith, because you have no bread?
9 Do you not yet perceive, neither 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 How is it that you do not perceive 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.
