Matthew 16:10-12

Revised Standard Version Catholic Edition

¹⁰ Or the seven loaves of the four thousand, and how many baskets you gathered? ¹¹ How is it that you fail to perceive that I did not speak about bread? Beware of the leaven of the Pharisees and Sad′ducees.” ¹² Then they understood that he did not tell them to beware of the leaven of bread, but of the teaching of the Pharisees and Sad′ducees.
