Luke 9:43

40 And I besought thy disciples to cast it out; and they could not.

41 And Jesus answered and said, O faithless and perverse generation, how long shall I be with you, and bear with you? bring hither thy son.

42 And as he was yet a coming, the demon dashed him down, and tare [him] grievously. But Jesus rebuked the unclean spirit, and healed the boy, and gave him back to his father.

43 And they were all astonished at the majesty of God. But while all were marvelling at all the things which he did, he said unto his disciples,

44 Let these words sink into your ears: for the Son of man shall be delivered up into the hands of men.

45 But they understood not this saying, and it was concealed from them, that they should not perceive it; and they were afraid to ask him about this saying.

46 And there arose a reasoning among them, which of them was the greatest.
