The Leaven of the Pharisees and Sadducees

5 When [fn]his disciples reached the other side of the sea, they realized that they had forgotten to bring bread. 6 Then Jesus said to them, “Watch out and beware of the leaven of the Pharisees and Sadducees.” 7 So they discussed this among themselves, saying, “He must have said this because we brought no bread.” 8 Aware of this, Jesus said [fn]to them, “Why are you discussing among yourselves, O you of little faith, the fact that you [fn]brought no bread? 9 Do you not yet understand? Do you not remember the five loaves for the five thousand, and how many baskets you collected? 10 Or the seven loaves for the four thousand, and how many baskets you collected? 11 How could you not understand that I was not [fn]talking about bread when I told you to beware of the leaven of the Pharisees and Sadducees?” 12 Then they understood that he had not told them to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees.
