Mark 8:16-18

8:16 And they reasoned among themselves, saying, [It is] because we have no bread. 8:17 And when Jesus knew [it], he saith unto them, Why reason ye, because ye have no bread? perceive ye not yet, neither understand? have ye your heart yet hardened? 8:18 Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?

Mark 8:32-33

8:32 And he spake that saying openly. And Peter took him, and began to rebuke him. 8:33 But when he had turned about and looked on his disciples, he rebuked Peter, saying, Get thee behind me, Satan: for thou savourest not the things that be of God, but the things that be of men.
