“Take heed and beware of the leaven of the Pharisees and Sadducees. ... O you of little faith, why reason you among yourselves, because you have no bread? Do you not yet perceive, neither remember the five loaves of the five thousand, and how many baskets you took up? Neither the seven loaves of the four thousand, and how many baskets you took up? How is it that you do not perceive that I spake not to you concerning bread? But beware of the leaven of the Pharisees and Sadducees.”
