“Watch out,” Jesus said to them, “beware of the yeast of the Pharisees and Sadducees.”

How could you not understand that I was not speaking to you about bread? But beware of the yeast of the Pharisees and Sadducees!”

Then they understood that he had not told them to be on guard against the yeast in bread, but against the teaching of the Pharisees and Sadducees.
