Mark 8:11-21

11The Pharisees came out and began to argue [contentiously and debate] with Him, demanding from Him a sign from heaven, to test Him [because of their unbelief].

12He groaned and sighed deeply in His spirit and said, “Why does this generation demand a sign? I assure you and most solemnly say to you, no sign will be given to this generation!”

13Leaving them, He again boarded the boat and left for the other side.

14Now the disciples had forgotten to bring bread, and they had only one loaf with them in the boat.

15Jesus repeatedly ordered them, saying, “Watch out! Beware of the leaven of the Pharisees and the leaven of Herod.”

16They began discussing this with one another, saying, “It is because we have no bread [that He said this].”

17Jesus, aware of this [discussion], said to them, “Why are you discussing [the fact] that you have no bread? Do you still not see or understand? Are your hearts hardened?

18Though you have eyes, do you not see? And though you have ears, do you not hear and listen [to what I have said]? And do you not remember,

19when I broke the five loaves for the five thousand, how many baskets full of broken pieces you picked up?” They answered, “Twelve.”

20“And [when I broke] the seven [loaves] for the four thousand, how many large baskets full of broken pieces did you pick up?” And they answered, “Seven.”

21And He was saying to them, “Do you still not understand?”
