Matthew 17:13-18 New American Standard Bible (NASB)

13. Then the disciples understood that He had spoken to them about John the Baptist.

14. When they came to the crowd, a man came up to Jesus, falling on his knees before Him and saying,

15. "Lord, have mercy on my son, for he is a lunatic and is very ill; for he often falls into the fire and often into the water.

16. I brought him to Your disciples, and they could not cure him."

17. And Jesus answered and said, "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."

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