Mark 9:31-34

31for he was teaching his disciples and telling them, “The Son of Man will be betrayed into the hands of men. They will kill him, and after three days he will rise.”

32But they did not understand this statement and were afraid to ask him.

33Then they came to Capernaum. After Jesus was inside the house he asked them, “What were you discussing on the way?”

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