5 When they crossed to the other side, the disciples forgot to take bread.
6 “Watch out!” Jesus told them. “Beware of the leaven of the Pharisees and Sadducees.”
7 They discussed this among themselves and concluded, “It is because we did not bring any bread.”
8 Aware of their conversation, Jesus said, “You of little faith, why are you debating among yourselves about having no bread?
9 Do you still not understand? Do you not remember the five loaves for the five thousand, and how many basketfuls you gathered?
10 Or the seven loaves for the four thousand, and how many basketfuls you gathered?
11 How do you not understand that I was not telling you about bread? But beware of the leaven of the Pharisees and Sadducees.”
12 Then they understood that He was not telling them to beware of the leaven used in bread, but of the teaching of the Pharisees and Sadducees.
