Luke 9:37-43

The next day, when they came down from the mountain, a large crowd met him. Just then a man from the crowd cried out, “Teacher, I beg you to look at my son, because he’s my only child. A 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. I begged your disciples to drive it out, but they couldn’t.” Jesus replied, “You unbelieving and perverse generation, how long will I be with you and put up with you? Bring your son here.” As the boy was still approaching, the demon knocked him down and threw him into severe convulsions. But Jesus rebuked the unclean spirit, healed the boy, and gave him back to his father. And they were all astonished at the greatness of God.
