Luke 9:37-42

On the next day, when they came down from the mountain, a large crowd met Him. [Matt 17:14-18; Mark 9:14-27] And a man from the crowd shouted for help, “Teacher, I beg You to look at my son, because he is my only child; and 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. I begged Your disciples to cast it out, but they could not.” Jesus answered, “You unbelieving and perverted generation! How long shall I be with you and put up with you? Bring your son here [to Me].” Even 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.
