Matthew 17:14-18

When they approached the crowd, a man came up to Jesus, kneeling before Him and saying, [Mark 9:14-27; Luke 9:37-42] “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. And I brought him to Your disciples, and they were not able to heal him.” And 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.” Jesus rebuked the demon, and it came out of him, and the boy was healed at once.
