Luke 9:38

35 And there was a voice from the cloud saying, This is my Son, the man of my selection; give ear to him.

36 And after the voice was gone they saw that Jesus was by himself. And they kept quiet, and said nothing at that time to anyone of the things which they had seen.

37 And on the day after, when they came down from the mountain, a great band of people came to him.

38 And a man from among them, crying out, said, Master, I make a request to you, give a thought to my son, for he is my only child:

39 And see, a spirit takes him, and suddenly he gives a cry, twisted in pain and streaming at the lips, and when it goes away from him at last, he is marked as from blows.

40 And I made a request to your disciples to send it out of him, but they were not able to do it.

41 And Jesus said, O generation without faith and false in heart, how long will I have to be with you and put up with you? let your son come here.
