Teaching of Pharisees

Mt 16:6 Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees. Mt 16:11 How is it that ye do not understand that I spake [it] not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees? Mt 16:12 Then understood they how that he bade [them] not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees. Mr 8:15 And he charged them, saying, Take heed, beware of the leaven of the Pharisees, and [of] the leaven of Herod.
