Luke 9:37-41

On the next day, when they came down from the mountain, a large crowd met Him.

And a man from the crowd shouted, saying, “Teacher, I beg You to look at my son, because he is my only son,

and a spirit seizes him and he suddenly screams, and it throws him into a convulsion with foaming at the mouth; and only with difficulty does it leave him, mauling him as it leaves.

And I begged Your disciples to cast it out, and they could not.”

And Jesus answered and said, “You unbelieving and perverse generation, how long shall I be with you and put up with you? Bring your son here.”
