Matthew 17:15-18

15“Lord, have mercy on my son, for he is a lunatic (moonstruck) and suffers terribly; for he often falls into the fire and often into the water.

16And I brought him to Your disciples, and they were not able to heal him.”

17And Jesus answered, “You unbelieving and perverted generation, how long shall I be with you? How long shall I put up with you? Bring him here to Me.”

18Jesus rebuked the demon, and it came out of him, and the boy was healed at once.
