Matthew 16:11-12

New King James Version

¹¹ How is it you do not understand that I did not speak to you concerning bread?—but to beware of the ^[a]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 ^[b]doctrine of the Pharisees and Sadducees.
