Matthew 17:14-18

At the foot of the mountain, a large crowd was waiting for them. A man came and knelt before Jesus and said, “Lord, have mercy on my son. He has seizures and suffers terribly. He often falls into the fire or into the water. So I brought him to your disciples, but they couldn’t heal him.” Jesus said, “You faithless and corrupt people! How long must I be with you? How long must I put up with you? Bring the boy here to me.” Then Jesus rebuked the demon in the boy, and it left him. From that moment the boy was well.
