Mark 9:31-34

31for he was teaching his disciples, saying to them, "The Son of Man is going to be delivered into the hands of men, and they will kill him. And when he is killed, after three days he will rise."

32But they did not understand the saying, and were afraid to ask him.

33And they came to Capernaum. And when he was in the house he asked them, "What were you discussing on the way?"

34But they kept silent, for on the way they had argued with one another about who was the greatest.
