Matthew 16:5-9 NIV

[5] When they went across the lake, the disciples forgot to take bread. [6] “Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.” [7] They discussed this among themselves and said, “It is because we didn’t bring any bread.” [8] Aware of their discussion, Jesus asked, “You of little faith, why are you talking among yourselves about having no bread? [9] Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many basketfuls you gathered?
