Matthew 16:8-11

8And Jesus knowing [it], said, Why reason ye among yourselves, O ye of little faith, because ye have taken no bread?

9Do ye not yet understand nor remember the five loaves of the five thousand, and how many hand-baskets ye took [up]?

10nor the seven loaves of the four thousand, and how many baskets ye took [up]?

11How do ye not understand that [it was] not concerning bread I said to you, Beware of the leaven of the Pharisees and Sadducees?
