He spoke another parable to them; The kingdom of heaven is like leaven which a woman took and hid in three sata [33 quarts] of flour, till the whole was leavened.

And Jesus said to them, Observe and beware of the leaven of the Pharisees and Sadducees.

Why do you not understand that I spoke to you not of bread, to beware of the leaven of the Pharisees and Sadducees?

Then they understood that he did not tell them to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees.
