Mark 9:18

18 Wherever it overpowers him, it throws him into a fit. He foams at the mouth, grinds his teeth, and stiffens up. So I spoke to your disciples to see if they could throw it out, but they couldn't."

Mark 9:18 Meaning and Commentary

Mark 9:18

And wheresoever he taketh him
The spirit, or devil, whether it be near fire, or water, whatsoever danger, or dangerous place:

he teareth him;
or throws him into it, or dashes him against it; or inwardly racks, tortures, and convulses him:

and he foameth;
at the mouth, like one that is mad:

and gnasheth with his teeth;
through the excessive pain he is in:

and pineth away;
his flesh is withered, dried up, and consumed away. This was the sad deplorable case this child was in, who was his father's only child, and therefore his health and life were very desirable: now he further observes to Christ, saying,

and I spake to thy disciples that they should cast him out, and
they could not.
Christ being absent, he entreated the disciples, who had power against unclean spirits, to cast them out; that they would make use of it, and dispossess this dumb and evil spirit; and who did make trial to cast him out, but were not able to effect it; (See Gill on Matthew 17:16).

Mark 9:18 In-Context

16 Jesus asked them, "What are you arguing about?"

17 Someone from the crowd responded, "Teacher, I brought my son to you, since he has a spirit that doesn't allow him to speak.

18 Wherever it overpowers him, it throws him into a fit. He foams at the mouth, grinds his teeth, and stiffens up. So I spoke to your disciples to see if they could throw it out, but they couldn't."

19 Jesus answered them, "You faithless generation, how long will I be with you? How long will I put up with you? Bring him to me."

20 They brought him. When the spirit saw Jesus, it immediately threw the boy into a fit. He fell on the ground and rolled around, foaming at the mouth.
