Luke 9:38-40

38And a man from the crowd shouted, saying, “Teacher, I beg You to look at my son, because he is my only son,

39and 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.

40And I begged Your disciples to cast it out, and they could not.”
