Luke 9:38-40

38Suddenly a man from the multitude cried out, saying, “Teacher, I implore You, look on 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 it departs from him with great difficulty, bruising him.

40So I implored Your disciples to cast it out, but they could not.”
