Mark 9:31

28 And when he had gone into the house, his disciples said to him privately, Why were we unable to send it out?

29 And he said to them, Nothing will make this sort come out but prayer.

30 And they went out from there, through Galilee; and it was his desire that no man might have knowledge of it;

31 For he was giving his disciples teaching, and saying to them, The Son of man is given up into the hands of men, and they will put him to death; and when he is dead, after three days he will come back from the dead.

32 But the saying was not clear to them, and they were in fear of questioning him about it.

33 And they came to Capernaum: and when he was in the house, he put the question to them, What were you talking about on the way?

34 But they said nothing: because they had had an argument between themselves on the way, about who was the greatest.
