Luke 9:37

34 And while he said these things, there came a cloud, and overshadowed them: and they feared as they entered into the cloud.

35 And a voice came out of the cloud, saying, This is my Son, my chosen: hear ye him.

36 And when the voice came, Jesus was found alone. And they held their peace, and told no man in those days any of the things which they had seen.

37 And it came to pass, on the next day, when they were come down from the mountain, a great multitude met him.

38 And behold, a man from the multitude cried, saying, Teacher, I beseech thee to look upon my son; for he is mine only child:

39 and behold, a spirit taketh him, and he suddenly crieth out; and it teareth him that he foameth, and it hardly departeth from him, bruising him sorely.

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