Luke 9:38-42

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

39and a spirit seizes him, and suddenly he cries out, and it throws him into a convulsion so that he foams at the mouth; and only with [great] difficulty does it leave him, mauling and bruising him as it leaves.

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

41Jesus answered, “You unbelieving and perverted generation! How long shall I be with you and put up with you? Bring your son here [to Me].”

42Even while the boy was coming, the demon slammed him down and threw him into a [violent] convulsion. But Jesus rebuked the unclean spirit, and healed the boy and gave him back to his father.
