Mark 9:30-32

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.
