Luke 9:37-43

The next day, when they came down from the mountain, a great crowd met Him. Suddenly a man cried out from the crowd, saying, “Teacher, I beg You, look upon my son, for he is my only child. A spirit seizes him, and he suddenly cries out. It convulses him until he foams at the mouth, and bruises him, and scarcely leaves him. I begged Your disciples to cast it out, but they could not.” Jesus said, “O faithless and perverse generation, how long shall I be with you and bear with you? Bring your son here.” While he was coming, the demon threw him down and convulsed him. But Jesus rebuked the unclean spirit, and healed the child, and returned him to his father. And they were all amazed at the mighty power of God.
