Mark 9:28-33
English Standard Version
Chapter 9
28And when he had entered the house, his disciples asked him privately, "Why could we not cast it out?" 29And he said to them, "This kind cannot be driven out by anything but prayer."
30They went on from there and passed through Galilee. And he did not want anyone to know,
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.
