10 The disciples asked him, ‘Why then do the teachers of the law say that Elijah must come first?’
11 Jesus replied, ‘To be sure, Elijah comes and will restore all things.
12 But I tell you, Elijah has already come, and they did not recognise him, but have done to him everything they wished. In the same way the Son of Man is going to suffer at their hands.’
13 Then the disciples understood that he was talking to them about John the Baptist.
14 When they came to the crowd, a man approached Jesus and knelt before him.
15 ‘Lord, have mercy on my son,’ he said. ‘He has seizures and is suffering greatly. He often falls into the fire or into the water.
16 I brought him to your disciples, but they could not heal him.’
