Matthew 16
6 Ref Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees.
7 Ref And they reasoned among themselves, saying, It is because we have taken no bread.
8 Ref Which when Jesus perceived, he said unto them, O ye of little faith, why reason ye among yourselves, because ye have brought no bread?
9 Ref Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up?
10 Ref Neither the seven loaves of the four thousand, and how many baskets ye took up?
11 Ref 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?
12 Ref 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.
