Mark 8:16

13 And having left them, having entered again into the boat, he went away to the other side;

14 and they forgot to take loaves, and except one loaf they had nothing with them in the boat,

15 and he was charging them, saying, `Take heed, beware of the leaven of the Pharisees, and of the leaven of Herod,`

16 and they were reasoning with one another, saying -- `Because we have no loaves.`

17 And Jesus having known, saith to them, `Why do ye reason, because ye have no loaves? do ye not yet perceive, nor understand, yet have ye your heart hardened?

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

19 When the five loaves I did brake to the five thousand, how many hand-baskets full of broken pieces took ye up?` they say to him, `Twelve.`
