Mark 8:11-21

11When the Pharisees heard that Jesus had arrived, they came and started to argue with him. Testing him, they demanded that he show them a miraculous sign from heaven to prove his authority.

12When he heard this, he sighed deeply in his spirit and said, “Why do these people keep demanding a miraculous sign? I tell you the truth, I will not give this generation any such sign.”

13So he got back into the boat and left them, and he crossed to the other side of the lake.

14But the disciples had forgotten to bring any food. They had only one loaf of bread with them in the boat.

15As they were crossing the lake, Jesus warned them, “Watch out! Beware of the yeast of the Pharisees and of Herod.”

16At this they began to argue with each other because they hadn’t brought any bread.

17Jesus knew what they were saying, so he said, “Why are you arguing about having no bread? Don’t you know or understand even yet? Are your hearts too hard to take it in?

18‘You have eyes—can’t you see? You have ears—can’t you hear?’ Don’t you remember anything at all?

19When I fed the 5,000 with five loaves of bread, how many baskets of leftovers did you pick up afterward?” “Twelve,” they said.

20“And when I fed the 4,000 with seven loaves, how many large baskets of leftovers did you pick up?” “Seven,” they said.

21“Don’t you understand yet?” he asked them.
