Luke 9:37-40

Suddenly a man from the multitude cried out, saying, “Teacher, I implore You, look on my son, for he is my only child. And behold, a spirit seizes him, and he suddenly cries out; it convulses him so that he foams at the mouth; and it departs from him with great difficulty, bruising him. So I implored Your disciples to cast it out, but they could not.”
