How can you fail to understand that I wasn't talking to you about bread? Beware of the yeast of the Pharisees and Sadducees!"

Then they understood that he did not say to beware of the yeast used in bread, but of the teaching of the Pharisees and Sadducees.

He told them another parable: "The kingdom from heaven is like yeast that a woman took and mixed with three measures of flour until all of it was leavened."

Jesus told them, "Watch out! Beware of the yeast of the Pharisees and Sadducees!"
