Matthew 17:14

12but 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.”

13Then the disciples understood that he spoke to them of John the Baptizer.

14When they came to the multitude, a man came to him, kneeling down to him and saying,

15“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.

16So I brought him to your disciples, and they could not cure him.”
