Matthew 17:15-18

15“Lord,” he said, “have mercy on my son, because he has seizures and suffers terribly. He often falls into the fire and often into the water.

16I brought him to your disciples, but they couldn’t heal him.”

17Jesus replied, “You unbelieving and perverse generation, how long will I be with you? How long must I put up with you? Bring him here to me.”

18Then Jesus rebuked the demon, and it came out of him, and from that moment the boy was healed.
