Matthew 16:5-12

⁵And when the disciples came to the other side, they had forgotten to take bread. ⁶And Jesus said to them, “Watch out and beware of the leaven of the Pharisees and Sadducees.” ⁷And they were discussing among themselves, saying, “We did not take bread.” ⁸But Jesus, knowing it, said, “Why are you discussing among yourselves, you of little faith, that you did not take bread? ⁹Do you not yet understand, nor remember the five loaves of the five thousand and how many baskets you took up? ¹⁰Nor the seven loaves of the four thousand and how many large baskets you took up? ¹¹How is it that you do not understand that I did not speak to you about bread? But beware of the leaven of the Pharisees and Sadducees.” ¹²Then they understood that he did not tell them to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees.
