Matthew 16:5-11

When the disciples reached the other side of the sea, they realized that they had forgotten to bring bread. Jesus said to them, “Watch out and be on your guard against the leaven of the Pharisees and Sadducees.” They began to discuss this among themselves, saying, “He said that because we did not bring bread.” But Jesus, aware of this, said, “You men of little faith, why are you discussing among yourselves that you have no bread? Do you still not understand or remember the five loaves for the five thousand, and how many baskets you picked up? Or the seven loaves for the four thousand, and how many large baskets you picked up? How is it that you fail to understand that I was not talking to you about bread? But beware of the leaven of the Pharisees and Sadducees.”
