Matthew 16

"A wicked and adulterous generation looks for a sign, but none will be given it except the sign of Jonah." Jesus then left them and went away. v. 4

"Do you still not understand?  Don't you remember the five loaves for the five thousand, and how many basketfuls you gathered? Or the seven loaves for the four thousand, and how many basketfuls you gathered? How is it you don't understand that I was not talking to you about bread?" v. 9-11a

When Jesus came to the region of Caesarea Philippi, he asked his disciples, "Who do people say the Son of Man is?"
They replied, "Some say John the Baptist; others say Elijah; and still others, Jeremiah or one of the prophets."
"But what about you?" he asked.  "Who do you say I am?"
Simon Peter answered, "You are the Messiah, the Son of the living God." v. 13-16

From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, the chief priests and the teachers of the law, and that he must be killed and on the third day be raised to life.  v. 21

Then Jesus said to his disciples, "Whoever wants to be my disciple must deny themselves and take up their cross and follow me.  For whoever wants to save their life will lose it, but whoever loses their life for me will find it." v. 24-25
