Another figure which he used with them was this: "The Kingdom of Heaven is like yeast, which a woman took and buried in a bushel of flour until it had all risen."

And Jesus said to them, "Look out, and be on your guard against the yeast of the Pharisees and Sadducees!"

Then they understood that he was warning them not against yeast but against the teaching of the Pharisees and Sadducees.
