Mark 9:28-31

²⁸And when he had entered into an house, his disciples asked him privily, Why might not we cast him out?

²⁹And he said to them, This kind in nothing may go out or This kind may not go out in anything, but in prayer and fasting.

³⁰And they went from thence, and went forth into Galilee; and they would not, that any man knew, or and he would not, that any man know.

³¹And he taught his disciples, and said to them, For man’s Son shall be betrayed into the hands of men, and they shall slay him, and he slain shall rise again on the third day.
