Matthew 17:14

Jesus answered them, “Elijah indeed comes first, and will restore all things;

but I tell you that Elijah has come already, and they didn’t recognize him, but did to him whatever they wanted to. Even so the Son of Man will also suffer by them.”

Then the disciples understood that he spoke to them of John the Baptizer.

“Lord, have mercy on my son, for he is epileptic and suffers grievously; for he often falls into the fire, and often into the water.

So I brought him to your disciples, and they could not cure him.”

Jesus answered, “Faithless and perverse generation! How long will I be with you? How long will I bear with you? Bring him here to me.”
