Mark 8:11-21

11And the Pharisees went out and began to dispute against him, seeking from him a sign from heaven, tempting him.

12And groaning in his spirit, he says, Why does this generation seek a sign? Verily I say unto you, A sign shall in no wise be given to this generation.

13And he left them, and going again on board ship, went away to the other side.

14And they forgot to take bread, and save one loaf, they had not [any] with them in the ship.

15And he charged them, saying, Take heed, beware of the leaven of the Pharisees and [of] the leaven of Herod.

16And they reasoned with one another, [saying], It is because we have no bread.

17And Jesus knowing [it], says to them, Why reason ye because ye have no bread? Do ye not yet perceive nor understand? Have ye your heart [yet] hardened?

18Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?

19When I broke the five loaves for the five thousand, how many hand-baskets full of fragments took ye up? They say to him, Twelve.

20And when the seven for the four thousand, the filling of how many baskets of fragments took ye up? And they said, Seven.

21And he said to them, How do ye not yet understand?
