Luke 9:38-40

38Just then a man from the crowd cried out, “Teacher, I beg you to look at my son, because he’s my only child.

39A spirit seizes him; suddenly he shrieks, and it throws him into convulsions until he foams at the mouth; severely bruising him, it scarcely ever leaves him.

40I begged your disciples to drive it out, but they couldn’t.”
