Jesus spoke plainly to his disciples about his coming death and resurrection.

Mark 8:31-33

31 Then Jesus began to teach them, “Even though I am the one who came from heaven, it is necessary that I suffer very much. It is also necessary that I be rejected by the elders, the chief priests, and the men who teach the Jewish laws {that the elders, the chief priests, and the men who teach the Jewish laws reject me}, and that I be killed {they kill me}. But on the third day after I am killed I will become alive again.” 32 He said this to them clearly. But Peter took Jesus aside and then, because he assumed that the Messiah would never die, he started to rebuke Jesus for talking about dying. 33 Jesus turned around and looked at his disciples. Then he rebuked Peter, saying, “Stop thinking like that! Satan is causing you to talk like that! Instead of wanting what God wants me to do, you are wanting me to do only what most people would want me to do.”
