Mark 8:31-35

And he began to teach them that the Son of man must suffer many things, and be rejected by the elders, and by the high priests, and the scribes, and be killed, and after three days rise again. And he spoke the word openly. And Peter, taking him aside, began to correct him. And turning away and looking at his disciples, he admonished Peter, saying, "Get behind me, Satan, for you do not prefer the things that are of God, but the things that are of men." And calling together the crowd with his disciples, he said to them, "If anyone chooses to follow me, let him deny himself, and take up his cross, and follow me. For whoever will have chosen to save his life, will lose it. But whoever will have lost his life, for my sake and for the Gospel, shall save it.
