Mark 9:31-34

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

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

33They came to Capernaum. When he was in the house, he asked them, “What were you arguing about on the way?”

34But they were silent, because on the way they had been arguing with one another about who was the greatest.
