Mark 8:11-21

11Then the Pharisees came and began to argue with Jesus, testing Him by demanding from Him a sign from heaven.

12Jesus sighed deeply in His spirit and said, “Why does this generation demand a sign? Truly I tell you, no sign will be given to this generation.” 13And He left them, got back into the boat, and crossed to the other side.

14Now the disciples had forgotten to take bread, except for one loaf they had with them in the boat. 15“Watch out!” He cautioned them. “Beware of the leaven of the Pharisees and of Herod.”

16So they began to discuss with one another the fact that they had no bread.

17Aware of their conversation, Jesus asked them, “Why are you debating about having no bread? Do you still not see or understand? Do you have such hard hearts? 18‘Having eyes, do you not see? And having ears, do you not hear?’1 And do you not remember? 19When I broke the five loaves for the five thousand, how many basketfuls of broken pieces did you collect?”

“Twelve,” they answered.

20“And when I broke the seven loaves for the four thousand, how many basketfuls of broken pieces did you collect?”

“Seven,” they said.

21Then He asked them, “Do you still not understand?”
