Luke 9:35-40
English Standard Version
Chapter 9
35And a voice came out of the cloud, saying, "This is my Son, my Chosen One; listen to him!" 36And when the voice had spoken, Jesus was found alone. And they kept silent and told no one in those days anything of what they had seen.
37On the next day, when they had come down from the mountain, a great crowd met him.
38And behold, a man from the crowd cried out, "Teacher, I beg you to look at my son, for he is my only child.
39And behold, a spirit seizes him, and he suddenly cries out. It convulses him so that he foams at the mouth, and shatters him, and will hardly leave him.
40And I begged your disciples to cast it out, but they could not."
