Bible Verses About The Sadducees: Cautioned his disciples against their principles

So when Yeshua said to them, "Watch out! Guard yourselves against the hametz of the P'rushim and Tz'dukim,"

How can you possibly think I was talking to you about bread? Guard yourselves from the hametz of the P'rushim and Tz'dukim!"

Then they understood -- they were to guard themselves not from yeast for bread but from the teaching of the P'rushim and Tz'dukim.
