11 And he answered and said, “Elijah indeed is coming, and will restore all things.
12 But I say to you that Elijah has already come, and they did not recognize him, but did with him whatever they wanted. In the same way also the Son of Man is going to suffer at their hands.”
13 Then the disciples understood that he had spoken to them about John the Baptist.
14 And when they came to the crowd, a man approached him, kneeling down before him
15 and saying, “Lord, have mercy on my son, because he has seizures and suffers severely, for often he falls into the fire and often into the water.
16 And I brought him to your disciples, and they were not able to heal him.”
17 And Jesus answered and said, “O unbelieving and perverse generation! How long will I be with you? How long must I put up with you? Bring him here to me!”
