Matthew 16:6-11

6“Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.” 7They discussed this among themselves and said, “It is because we didn’t bring any bread.” 8Aware of their discussion, Jesus asked, “You of little faith, why are you talking among yourselves about having no bread? 9Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many basketfuls you gathered? 10Or the seven loaves for the four thousand, and how many basketfuls you gathered? 11How is it you don’t understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees.”
