Matthew 16:6-12 New King James Version (NKJV)

⁶ Then Jesus said to them, “Take heed and beware of the ^[a]leaven of the Pharisees and the Sadducees.”

⁷ And they reasoned among themselves, saying, “It is because we have taken no bread.”

⁸ But Jesus, being aware of it, said to them, “O you of little faith, why do you reason among yourselves because you ^[b]have brought no bread? ⁹ Do you not yet understand, or remember the five loaves of the five thousand and how many baskets you took up? ¹⁰ Nor the seven loaves of the four thousand and how many large baskets you took up? ¹¹ How is it you do not understand that I did not speak to you concerning bread?—but to beware of the ^[c]leaven of the Pharisees and Sadducees.” ¹² Then they understood that He did not tell them to beware of the leaven of bread, but of the ^[d]doctrine of the Pharisees and Sadducees.
