“While the boy

Was coming to Jesus,

The demon threw him down

With convulsions.

But Jesus rebuked

The unclean spirit.

He healed the boy.

He gave him back

To his father.”

ἔτι δὲ προσερχομένου αὐτοῦ ἔρρηξεν αὐτὸν τὸ δαιμόνιον καὶ συνεσπάραξεν· ἐπετίμησεν δὲ ὁ Ἰησοῦς τῷ πνεύματι τῷ ἀκαθάρτῳ, καὶ ἰάσατο τὸν παῖδα καὶ ἀπέδωκεν αὐτὸν τῷ πατρὶ αὐτοῦ.

Luke said that while the young man was coming to Jesus (ἔτι δὲ προσερχομένου αὐτοῦ), the demon threw him down to the ground (ἔρρηξεν αὐτὸν τὸ δαιμόνιον) with convulsions (καὶ συνεσπάραξεν).  But Jesus rebuked the unclean spirit (πετίμησεν δὲ ὁ Ἰησοῦς τῷ πνεύματι τῷ ἀκαθάρτῳ).  He healed the boy (καὶ ἰάσατο τὸν παῖδα).  He gave him back to his father (καὶ ἀπέδωκεν αὐτὸν τῷ πατρὶ αὐτοῦ).  Both Matthew, chapter 17:18 and Luke here have a summary of a more detailed longer statement from Mark, chapter 9:20-27, about this mute epileptic boy.  Mark said that they brought the boy to Jesus.  However, when the evil spirit saw Jesus, it immediately convulsed the boy.  The boy fell on the ground and began to roll around, foaming at the mouth.  In fact, Jesus got to see what the father had described to him earlier.  Jesus asked the father of this boy how long had these convulsions been happening to him.  The father said that it had been happening since his childhood.  This evil spirit would often cast him into both fire and water, as Matthew had mentioned, in order to destroy him.  Then the father asked Jesus, if he was able to do anything to help his son.  He wanted Jesus to have pity and compassion on him and his son.  Jesus said to him that all things could be done for the one who believed.  Belief was the key ingredient for any success in this area.  The father of the child cried out that he believed, but he wanted help with his unbelief.  This was a strong statement of belief that also recognized unbelief at the same time.  Jesus rebuked the unclean spirit.  He directly commanded this unclean evil spirit that had kept this boy from speaking and hearing to come out of him, never again to enter him.  Jesus then got rid of the unclean spirit that was in this boy in a public act in front of a crowd.  After crying out and terribly convulsing the boy with spasms, the evil spirit came out of the boy, who became a corpse.  Most of the people said that the boy was dead.  Could this boy live without the evil spirit in him?  Jesus took the boy by the hand.  He lifted him up, so that he rose up, and was able to stand up on his feet by himself.  The boy was not dead.  There was a clear equivalence between the illness of epilepsy and demonic possession.  Once the devil or evil spirits had left the boy, he was cured of his various ailments.  Have you ever dealt with an epileptic?
