Luke 9:37

33As they were parting from him, Peter said to Jesus, “Master, it is good for us to be here. Let’s make three tents: one for you, one for Moses, and one for Elijah,” not knowing what he said.

34While he said these things, a cloud came and overshadowed them, and they were afraid as they entered into the cloud.

35A voice came out of the cloud, saying, “This is my beloved Son. Listen to him!”

36When the voice came, Jesus was found alone. They were silent, and told no one in those days any of the things which they had seen.

37On the next day, when they had come down from the mountain, a great multitude met him.

38Behold, a man from the crowd called out, saying, “Teacher, I beg you to look at my son, for he is my only born child.

39Behold, a spirit takes him, he suddenly cries out, and it convulses him so that he foams; and it hardly departs from him, bruising him severely.

40I begged your disciples to cast it out, and they couldn’t.”

41Jesus answered, “Faithless and perverse generation, how long shall I be with you and bear with you? Bring your son here.”
