Matthew 17:15-19

“Lord, have mercy on my son, because he has seizures and suffers terribly; for he often falls into the fire and often into the water.

And I brought him to Your disciples, and they could not cure him.”

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

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

Then the disciples came to Jesus privately and said, “Why could we not cast it out?”
